Question

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

Explanation:

Step1: Substitute \( x = -1 \) into \( f(x) \)

Given \( f(x) = -x^2 \), replace \( x \) with \( -1 \). So we have \( f(-1) = -(-1)^2 \).

Step2: Calculate the exponent first

First, calculate \( (-1)^2 \). By the definition of squaring a number, \( (-1)^2 = (-1) \times (-1) = 1 \).

Step3: Multiply by -1

Now, multiply the result by -1: \( f(-1) = -1 \times 1 = -1 \).

Answer:

\( -1 \)
