Intro to Piecewise

Explain in your own words how to evaluate the function for f(-5)

Explain in your own words how to evaluate the function for f(2)

Evaluate the function when x = 4

• f(4) = 2(4) - 5 = 3

• f(4) = 2(4) - 5 = -1

• f(4) = ½(4) + 1 = 3

• f(4) = 4

• 6

• 5

• -7

• 0

Evaluate the function when x = 6

• f(6) = -5

• f(6) = 4

• f(6) = 2

• f(6) = 7

What is the value of f(0)?

• -2

• 2

• 4

• 0

Find g(4)

• g(4) = 4

• g(4) = -4

• g(4) = 2

• g(2) = 4
