Answer:

The correct options are C and D

C. A translation of 5 units up

D. A reflection about the x-axis

Step-by-step explanation:

We have been given as function of the graph:

f(x) = x²

Which is transformed into the function

g(x) = -(x-2)² + 5

Consider the graph of y = x²

To convert it into the graph of given transformed function.

First reflect the graph over x-axis, the equation becomes

y = -(x)²

Then translate the graph 2 units to the right

y = -(x - 2)²

Then translate the graph 5 units up.

y = -(x - 2)² + 5

Thus, the correct statements are C and D

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t^2+64t+80 gives the height, in feet, of the ball
Wewaii [24]

Answer:

<h3>5 seccs</h3>

Step-by-step explanation:

Given the modeled function of the height expressed as;

h(t)=-16t^2+64t+80

The ball hits the ground when h(t) = 0 (when the height is zero)

Substitute into the function and find t;

0 =-16t^2+64t+80

divide through by -16

0 = t²-4t-5

Factorize;

t²-4t-5 = 0

t²-5t+t-5 = 0

t(t-5)+1(t-5) = 0

(t+1)(t-5) = 0

t + 1 = 0 and t-5 = 0

t = -1 and t = 5

Time can't be negative

Hence it will take the ball 5secs before it hits the ground
