CCSS.HSF.IF.B.5

Is this a Function?

Why or Why Not?

• The graph does represent y as a function of x because the x values do not repeat.

• The graph does NOT represent y as a function of x because the x values repeat.

• The graph does represent y as a function of x because the y values do not repeat.

• The graph does NOT represent y as a function of x because the y values repeat.

What is the ZERO of the function?

• (0, 2)

• (2, 0)

• (1,0)

• (0, 1)

Look at the sequence. Which expression represents the nth term? 25, 21, 17, 13

• f(1) = 25 f(n) = f(n-1) + 4

• f(1) = -4 f(n) = f(n-1) + 25

• f(1) = 25 f(n) = f(n-1) - 4

• f(1) = -4 f(n) = f(n-1) + 25
