Q(x)= x^2-6x+3, find Q(-3)
I REALLY DON'T KNOW WHAT THE HECK ITS ASKING FOR
put -3 in for x, and compute
(-3)^2-6(-3)+3
THANKS!!!!!!! :) I FEEL SO STUPID! LOL
No problem! I'll explain step-by-step how to find the value of Q(-3) using the given quadratic function Q(x) = x^2 - 6x + 3.
To find Q(-3), we need to substitute -3 into the equation for x. So, wherever we see 'x' in the equation, we replace it with -3.
Step 1: Replace 'x' with -3 in the equation:
Q(-3) = (-3)^2 - 6(-3) + 3
Step 2: Simplify the equation:
Q(-3) = 9 + 18 + 3
Q(-3) = 30
Therefore, the value of Q(-3) is 30.
