We have that
$y=- x^{2} +36$

we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum

step 1
convert the equation of the parabola in the vertex form
$y=- x^{2} +36 \\ y-36=- x^{2}$

the vertex (h,k) is the point (0,36)

Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)

Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0
$- x^{2} +36=0 \\ x^{2} =36 \\ x= (+/-) 6$

the points are (-6,0) and (6,0)

see the attached figure

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1

mario62 [17]

Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: $\mathbf{y = kx - 2}$

When k = 1,

We have:

$\mathbf{y = 1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = x - 2}$

So, the equation is: $\mathbf{y = x - 2}$ when k = 1

When k = 0.4,

We have:

$\mathbf{y = 0.4\times x - 2}$ ----- substitution property of equations

$\mathbf{y = 0.4x - 2}$

So, the equation is: $\mathbf{y = 0.4x - 2}$ when k = 0.4

When k = -1,

We have:

$\mathbf{y = -1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = -x - 2}$

So, the equation is: $\mathbf{y = -x - 2}$ when k = -1

See attachment for the graphs of: $\mathbf{y = x - 2}$ , $\mathbf{y = 0.4x - 2}$ and $\mathbf{y = -x - 2}$
