Q. 4646.) The graph of f f includes the point (2,6) (2,6) and the slope of the tangent line to f f at any point x x is given by the expression 3x+4 3 x+4 . Find f(2) f(-2) .
  1. Integrate slope function: To find f(2)f(-2), we need to integrate the given slope function 3x+43x+4 to get the general form of f(x)f(x). The slope function represents the derivative of f(x)f(x), so we will integrate 3x+43x+4 with respect to xx.
  2. Find general form of \newlinef(x)f(x): The integral of \newline3x3x with respect to \newlinexx is \newline(3/2)x2(3/2)x^2, and the integral of \newline44 with respect to \newlinexx is \newline4x4x. We also need to add a constant of integration, which we'll call \newlineCC.
  3. Use point (2,6) (2,6) to find C C : So the general form of f(x) f(x) after integration is f(x) = \frac{\(3\)}{\(2\)}x^\(2 + 44x + C \.
  4. Calculate specific form of (x) : We are given that the graph of i includes the point (22,66) . We can use this information to find the value of the constant C by substituting x=22 and f(x)=66 into the equation.
  5. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = \left(\frac{3}{2}\right)(2)^2 + 4(2) + C.
  6. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = \left(\frac{3}{2}\right)(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = \left(\frac{3}{2}\right)(4) + 8 + C.
  7. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = (\frac{3}{2})(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C.
  8. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = (\frac{3}{2})(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C. Subtracting 1414 from both sides, we find C=614C = 6 - 14, which gives us C=8C = -8.
  9. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = (\frac{3}{2})(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C. Subtracting 1414 from both sides, we find C=614C = 6 - 14, which gives us C=8C = -8. Now that we have the value of CC, we can write the specific form of f(x)f(x) as f(2)f(-2)00.
  10. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = (\frac{3}{2})(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C. Subtracting 1414 from both sides, we find C=614C = 6 - 14, which gives us C=8C = -8. Now that we have the value of CC, we can write the specific form of f(x)f(x) as f(2)f(-2)00. To find f(2)f(-2), we substitute f(2)f(-2)22 into the equation f(2)f(-2)00.
  11. Substitute x=2x=-2 to find f(2)f(-2): Substituting the values, we get 6=(32)(2)2+4(2)+C6 = (\frac{3}{2})(2)^2 + 4(2) + C. Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C. Subtracting 1414 from both sides, we find C=614C = 6 - 14, which gives us C=8C = -8. Now that we have the value of CC, we can write the specific form of f(x)f(x) as f(2)f(-2)00. To find f(2)f(-2), we substitute f(2)f(-2)22 into the equation f(2)f(-2)00. Substituting, we get f(2)f(-2)44.

Simplifying the equation, we get 6=(32)(4)+8+C6 = (\frac{3}{2})(4) + 8 + C. This simplifies to 6=6+8+C6 = 6 + 8 + C. Subtracting 1414 from both sides, we find C=614C = 6 - 14, which gives us C=8C = -8. Now that we have the value of CC, we can write the specific form of f(x)f(x) as f(2)f(-2)00.
