Question

What is the value of f(x) = –x^2 – 2 when x = –1?

Answer 1

= -3

Explanation:

if x equals -1 then we have to plug it in.

f(x) = –x^2 – 2

f(x) = -1^2-2

which equal -3

Answer 2

-1

Explanation:

If x=-1, then we substitute it into the equation. -(-1)^2 is just 1, minus 2 is -1

f(x) = -1
