Acoordinate grid is mapped onto a video game screen, with the origin at the lower left corner. the game designer programs a turtle to move along a linear path that passes through the points (0, 0) and (10, 8).

the designer also programs a bird with a path that can be modeled by a quadratic function. the bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).

what are the values of the constants in the vertex form of the quadratic equation that models the bird's path?

h=
k=
a=

The bird follows a parabolic path.

The values of h, k and a are:      

The given parameters are:

--- a point on the path

The vertex of a quadratic function is represented as:

Vertex = (h,k)

So, by comparison:

The general equation of parabola is:

Substitute values for h and k

Substitute

Subtract 20 from both sides

Divide both sides by 100

So, we have:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
