Q. Given h(x)=4x−4 h(x)=4 x-4 , find h(−5) h(-5) .\newlineAnswer:
  1. Substitute xx with −5-5: To find the value of h(−5)h(-5), we need to substitute xx with −5-5 in the function h(x)=4x−4h(x) = 4x - 4.\newlineh(−5)=4(−5)−4h(-5) = 4(-5) - 4
  2. Perform multiplication and subtraction: Now, we perform the multiplication and subtraction.\newlineh(−5)=(4×−5)−4h(-5) = (4 \times -5) - 4\newlineh(−5)=−20−4h(-5) = -20 - 4
  3. Add the numbers together: Finally, we add the two numbers together to get the final result.\newlineh(−5)=−20−4h(-5) = -20 - 4\newlineh(−5)=−24h(-5) = -24
