Question

How do you do this problem step by step I'm confused
f(x)=x^2-10+4;f(-2)

Answer 1

-10

Explanation:

f(x) = f(-2)

(-2) × 2 - 10 + 4

= (-4) - 10 + 4

= (-14) + 4

= (-10)

Answer 2

Explanation:

Add the numbers first. (-10 + 4)

f(x)=x^2-10+4;f(-2)

f(x)=x^2-6;f(-2)

Then re-order the terms so that the constants are on the left. f & (-2)

f(x)=x^2-6;f(-2)

f(x)=x^2-6;-2f

Your answer will then be f(x)=x^2-6;-2f.
