re-write the quadratic function below in standard form\n$y = 3(x - 1)^2 - 8$
Answer
Explanation:
Step1: Expand $(x-1)^2$
$(x-1)^2 = x^2 - 2x + 1$
Step2: Multiply by 3
$3(x^2 - 2x + 1) = 3x^2 - 6x + 3$
Step3: Subtract 8
$3x^2 - 6x + 3 - 8$
Step4: Simplify constants
$3x^2 - 6x - 5$
Answer:
$y = 3x^2 - 6x - 5$
