Does this graph represent a function or not? Explain.
Not a Function. It does not pass the vertical line test. There are x-values with more than one y-value.

Evalutae h(x) = 3x - 24
for h(-2)
-30
100
Write the linear function.
f(x) = 6x
200
State the domain.
all real numbers
200
Evaluate the function t(x) for t(3).

200
Write a function for the values in the table.
f(x) = 2x - 7
300
List the values of the range.
-2, 2, 6, 10, 14
300
Evaluate the function p(x) for p(0)

What is the linear equation in slope-intercept form of this function?
y = (-1/3)x + 5
400
If the ordered pair (5,6) is added to the graph, will it be a function or not? Explain.
Not a function. One input 5 has two outputs (0 and 6).
400
Evaluate the function for f(5)
f(x) = 2x2 - 3x + 7
42
400
Write the equation in function notation. Leave numbers as integers or fractions.
f(x) = -3/2x + 23/2
500
Does the table represent a linear or nonlinear function? Explain.
Nonlinear. The pattern does not add a constant amount in the y-column.

Evaluate the function j(x) for x = -3
j(x) = -4x2 - x - 1
-34
500
Write the function given the 2 points on the graph. Then evaluate the function for f(21).
f(x)=-2x+8
f(21) = -34
