Remediation - Unit 5A Test

The functions

 $f\left(x\right)\ =\ x$   $g\left(x\right)\ =\ x^2$  

are graphed on the coordinate plane above. For which x-values is f(x) > g(x)?
Hint: f(x) is red and g(x) is blue

• 0 < x < 1

• x < 0

• x > 1

• x < 0 and x < 1

The functions of h(x) and k(x) are graphed below on the coordinate plane above:

 $h\left(x\right)\ =\ \left(x\ -1.5\right)^2\ -\ 1$  (black)

 $k\left(x\right)\ =\ 2^{\left(x-2\right)\ }+\ 1$  (red)

For what x-values is k(x) > h(x)?

• 0 < x < 4

• x < 1

• x > 0

• 1 < x < 3

Jason threw a ball in the air from the roof of Meadowcreek High School. The graph shows the relationship between the number of seconds that the ball was in the air and the height of the ball.

What is the x-intercept for the given function? What does this represent in the situation?

• 4 seconds, the number of seconds it takes for the ball to hit the ground

• 4 seconds, the height which Jason threw the ball

• 76 seconds, the number of seconds it took for the ball to hit the ground

• 76 seconds, the height which Jason threw the ball
