I'm assuming that you want to find f(-2) and f(8) right?


Let's find f(-2):


f%28x%29=4x-10 Start with the function.


f%28-2%29=4%28-2%29-10 Plug in x=-2.


f%28-2%29=-8-10 Multiply 4 and -2 to get -8.


f%28-2%29=-18 Combine like terms.







Now let's find f(8):


f%28x%29=4x-10 Start with the function.


f%288%29=4%288%29-10 Plug in x=8.


f%288%29=32-10 Multiply 4 and 8 to get 32.


f%288%29=22 Combine like terms.
