question
given $f(x) = -x^2$, find $f(-10)$
answer attempt 1 out of 2

Explanation:

Step1: Substitute \( x = -10 \) into \( f(x) \)

We have the function \( f(x) = -x^2 \). To find \( f(-10) \), we substitute \( x = -10 \) into the function. So we get \( f(-10)=-(-10)^2 \).

Step2: Calculate the square of \( -10 \)

First, calculate \( (-10)^2 \). By the definition of squaring a number, \( (-10)^2=(-10)\times(-10) = 100 \). Then our expression becomes \( f(-10)=- 100 \).

Answer:

\(-100\)
