Question

multiple-choice question when x = -1, what is the corresponding y - value? y = -2 y = 1 y = 0 y = -3

Explanation:

Step1: Identify the function

The function is $y = x^2 + 4x + 1$.

Step2: Substitute $x=-1$

Substitute $x=-1$ into the function:
$y = (-1)^2 + 4(-1) + 1$

Step3: Calculate each term

Calculate each part:
$(-1)^2 = 1$, $4(-1) = -4$

Step4: Sum the terms

Add the results together:
$y = 1 - 4 + 1$
$y = -2$

Answer:

y = -2
