Solving Function Notations

If f(x) = 7, what is the value of x?

6x - 5 = f(x)

• 2

• 3

• 6

• 12

Given f(x) = -x + 12, find f(-2).

Given f(x) = -5x - 15, find f(4).

Find the output.

• 17

• 55

• 30

• 37

Given the graph, find:

• No; it is not a straight line.

• Yes; it passes the vertical line test.

• No; there is a line connecting the dots.

Which graph is not a function?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

• x=3

• x= 0.5

• x= -3.5 and 0.5
