Aparabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.
which graph matches this description?

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

we have

An x-intercept of (-1,0)

substitute and solve for a

The equation is

Verify the y-intercept

For x=0

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

see the attached figure

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
