Question

F(x)=-9x+8 then f(-2)=?

Answer 1

Answer:

26

Step-by-step explanation:

the function is f(x), and we need to find f(-2). the only difference between the two terms i gave is the -2 replacing the x. this means that you must replace every x in the first equation with -2. this makes the new function f(-2)=-9(-2)+8. after multiplying the -9 and -2 and adding that product to 8, you come up with your answer: 26.
