William is comparing the graphs of

 $y=3^x$  and  $y=5^x$  . Which statement is true?

• the y-intercept of  $y=3^x$  is (0,3) and the y-intercept of  $y=5^x$  is (0,5)

• Both graphs have a y-intercept of (0,1) but  $y=3^x$  is steeper

• Both graphs have a y-intercept of (0,1) but  $y=5^x$  is steeper

• Neither graph has a y-intercept

• parabola
• asymptote
• rational function
• None of these

The function has an asymptote at y = -1. What is the end behavior of the function?

• As x decreases, f(x) approaches but never reaches -1.

  As x increases, f(x) increases

• As x decreases, f(x) approaches but never reaches 0.

  As x increases, f(x) increases

• As x decreases, f(x) approaches but never reaches -1.

  As x increases, f(x) decreases

• As x decreases, f(x) decreases.

  As x increases, f(x) approaches but never reaches -1.

Estimate the intercept(s) of the function. What does the intercept represent in context?

Select ALL that apply

• no x-intercept

• y-intercept (0, 300,0000); the original value of the equipment was $300,0000

• x - intercept (0, 300,0000); the original value of the equipment was $300,0000

• no y-intercept

CCSS.HSF.LE.B.5

Why are the x-values nonnegative?

• x values represent years, years cannot be negative.

• x-values represent value, value cannot be negative

• the graph doesn't show the negative side of the x-axis

Estimate f(1). Explain what it's value means in the given context.

• f(1) =32; After 1 round 32 teams remain

• f(1) = 1; After 1 round 1 team remains

• f(1) = 32; After 32 rounds 1 team remains

• f(1) = 10; After 1 round 10 teams remain
