It would be easier if you use a website with a graph! There is a website called "desmos" and if you search up desmos graphing calculator you will find it. Type in the points in the website, and it would add in the points for you.
but here is a piece of key information:
Make into a decimal. That would be 0.75.
Since it says "of the way from", count the boxes in the graph from each point.
Hope this helps! ^.^
Answer:
vertex = (- 2, - 36)
Step-by-step explanation:
Given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
f(x) = 5x² + 20x - 16 is in standard form
with a = 5, b = 20 and c = - 16
= -
= - 2
Substitute x = - 2 into f(x) for corresponding y- coordinate
f(- 2) = 5(- 2)² +20(- 2) - 16 = 20 - 40 - 16 = - 36
vertex = (- 2, - 36)
