Interpret Functions

Which of the following points is a y-intercept?

• (-9,0)

• (-2,3)

• (4,-2)

• (0,5)

Name the x-intercept(s)?

• (0, 0)

• (2, 4)

• (0, 0) and (0, 4)

• (0, 0) and (4, 0)

given f(x) = x² - 2x, find f(4)

• 0
• 24
• 8
• und.

given f(x) = x² + 2x, find f(a - 3)

• a² -4a +3
• a² + 2a -15
• a² + 8a + 3
• a² - 4a + 6

which is a function

• a
• b
• c
• d

Use the graph of f to find the domain and range of the function.

• D = (−3, 3], R = [–3, 0]

• D = [−3, 3), R = [–3, 0]

• D = (−3, 3), R = [–3, 0]

• D = [−3, 3], R = [–3, 0]

Is this mapping a function or not a function? 

• Function
• Not a Function

Use the graph to test for symmetry.

• symmetric with respect to x-axis

• symmetric with respect to y-axis

• symmetric with respect to origin

• symmetric with respect to x-axis, y-axis and origin

Describe what kind of symmetry the graph appears to have.

• x-axis symmetry

• y-axis symmetry

• origin symmetry

• no symmetry

• y-axis symmetry

• x-axis symmetry

• origin symmetry

• None of these symmetries

• All 3 of these symmetries
