Answer
a) f(5) = 12
b) f(-1) = 6
c) f(-3) = 4
Explanation
We are given the function
f(x) = x + 7
We are then asked to evaluate a number of valus of x for the function
a) f(5)
f(x) = x + 7
f(5) = 5 + 7 = 12
b) f(-1)
f(x) = x + 7
f(-1) = -1 + 7 = 6
c) f(-3)
f(x) = x + 7
f(-3) = -3 + 7 = 4
Hope this Helps!!!
