-7
f(x)=4x+5
Let x =-3
f(-3)=4*-3+5
Multiply
f(-3)=-12+5
Add
f(-3) = -7
C.
To find the slope when you know two points, use this formula:
M = y₂ - y₁ ÷ x₂ - x₁
M = (4 - (-8)) ÷ (0 - (-7))
M = 12 ÷ 7
M =

week 1 - 62,68,68,68,69,70,70,72,72,75,75,76,78,78,80,80,80,89,89
week 2 - 62,68,68,68,69,70,70,72,72,72,75,75,76,78,78,80,80,80,85,86,86,86,88,88, 88,88,89,89,89,89
(bold = median)
week 2 median = 79 > week 1 median = 75
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
The standard form: ax^2 + bx + c
