Question

find the values for the given equation, y = x^3+3
find y when x = -1
2
4

next question

Explanation:

Step1: Substitute x = -1 into the equation

We have the equation \( y = x^3 + 3 \). Substitute \( x = -1 \) into it, so we get \( y = (-1)^3 + 3 \).

Step2: Calculate the value of \( (-1)^3 \)

Recall that \( (-1)^3 = -1\times -1\times -1 = -1 \). Then the equation becomes \( y = -1 + 3 \).

Step3: Calculate the sum

\( -1 + 3 = 2 \), so \( y = 2 \).

Answer:

The value of \( y \) when \( x = -1 \) is 2, so we should select the option with 2 (the first checkbox option: 2).
