Question

Find f(-2) if f(x)=x²+3 *remember, any number squared is...

a) -1
b) 7
c) 1
d) -7
e) Other

Answer 1

To find f(-2), substitute -2 into the function f(x) = x² + 3. The answer is 7 (option b).

Step-by-step explanation:

To find f(-2), we substitute -2 into the function f(x) = x² + 3. So, we get:

f(-2) = (-2)² + 3 = 4 + 3 = 7

Therefore, the answer is 7 (option b).
