Answer:
f(x) = (x - 2)² - 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 4x + 3
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 4x
f(x) = x² + 2(- 2)x + 4 - 4 + 3
= (x - 2)² - 1
The rate is 12 per carton.
The sign of "a" tells you the direction of the parabola.
Answer:
Jill did not change the symbol of inequality from minor (< ) to major (>) in the Step 4
Step-by-step explanation:
we have
step 1
Multiply by 12 both sides
step 2
Group terms
step 3
Combine like terms
step 4
Divide by -7 both sides
Remember that when you multiply an inequality by -1 the < symbol changes to the > symbol
so
Jill did not change the symbol of inequality from minor (< ) to major (>) in the Step 4
