Question

determine the value of y, if x is -10.
y = x² + 6

Explanation:

Step1: Substitute x with -10

We know that \( x = -10 \), so we substitute \( x \) in the equation \( y = x^2 + 6 \) with -10. So we get \( y = (-10)^2 + 6 \).

Step2: Calculate the square of -10

The square of -10, \( (-10)^2 \), is calculated as \( (-10)\times(-10)=100 \). So now the equation becomes \( y = 100 + 6 \).

Step3: Add the numbers

Adding 100 and 6, we get \( 100 + 6 = 106 \). So \( y = 106 \).

Answer:

106
