On a coordinate plane, a parabola opens up. It goes through (negative 8, 0), has a vertex at (negative 5, negative 9), and goes through (negative 2, 0). Zander was given two functions: the one represented by the graph and the function f(x) = (x + 4)2. What can he conclude about the two functions? They have the same vertex. They have one x-intercept that is the same. They have the same y-intercept. They have the same range.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
