Review Algebra B

Is this function increasing or decreasing?

• Increasing

• Decreasing

Answer explanation

This function is increasing, because as you move from left to right, the y-value get bigger.

What is the x-intercept of this function?

Answer explanation

The function crosses the x-axis at x=1.

Is this function increasing or decreasing?

• Increasing

• Decreasing

Answer explanation

This function is decreasing, because as you move from left to right, the y-values get smaller.

What is the asymptote of this function?

• y=-3

• x=-3

• x=0

• y=0

Answer explanation

The blue line in the picture represents the asymptote. This is the line y=0, since all points on this line have a y-value of 0.

• (0, 1)

• (0, 3)

• x= 0

• y = 0

What is the y-intercept of the function?

• none

• all real numbers

• (0, 80)

What is the domain of the following function?

• y>1

• y = 1

• all real numbers

Given the equation below determine the asymptote.

• (0, 1)

• (0, 3)

• x= 0

• y = 0

What is the y-intercept?

• (0,0)

• (0,1)

• (-3,0)

• (0,-3)
