WebYour function g(x) is defined as a combined function of g(f(x)), so you don't have a plain g(x) that you can just evaluate using 5. The 5 needs to be the output from f(x). So, start by finding: 5=1+2x That get's you back to the original input value that you can then use as the input to g(f(x)). Subtract 1: 4=2x Divided by 2: x=2 WebIf f′(2)=3, and g(x)=9f(x), what is g′(2)? Do not include "g′(2)=" in your answer. For example, if you found g′(2)=7, you would enter 7. Expert Answer.

Step 2: Find f (g (3)) by using g (3) as input for f (x). f (g (3)) = f (9) = 2 (9) + 3 = 18 + 3 = 21. We can visualize this process using the following figure easily. Thus: To find f (g (x)), substitute x = g (x) into f (x). miflash rom
