Answer:
Step-by-step explanation:
The expression f(x) means that the function y is in terms of x; that is to say that x is the independent variable that will change, as it changes, y changes along with it. Replacing x with what we want to evaluate the function at is how we solve this. If we replace x with a 1, our function is:
[tex]f(1)=2^1+8[/tex]
2 to the 1st power is 2, and add 8 to that and you get that
f(1) = 10
