Q. Use the following function rule to find f(a7)f(a - 7). Simplify your answer.\newlinef(x)=2xf(x) = -2x\newlinef(a7)=f(a - 7) = ______
  1. Substitute in function: We are given the function f(x)=2xf(x) = -2x and we need to find f(a7)f(a - 7). To do this, we substitute (a7)(a - 7) for xx in the function rule.\newlinef(a7)=2(a7)f(a - 7) = -2(a - 7)
  2. Distribute 2-2: Now we distribute the 2-2 to both terms inside the parentheses.f(a7)=2×a+2×7f(a - 7) = -2 \times a + 2 \times 7
  3. Simplify expression: Simplify the expression by multiplying 2-2 with aa and 77.\newlinef(a7)=2a+14f(a - 7) = -2a + 14
