What is x when g(x) = 7?
x = 4
What is h(2)?
h(2) = 3 meaning when the input is 2, the output is 3.
What is f(1)?
f(1) = -3
How is this math sentence "f(x+1)=5(x+2) spoken? Write your answer in words.
F of x plus one equals 5 groups of x plus 2.
Is this a linear function?
No. It is a function, but it's an nonlinear function because it is not a straight line.
If the input is 4, what is the output?
7
14
Is this discrete or continuous?
Is this a function?

What's the difference between the interval of the x-axis and x-intercept?
Interval of the x-axis: The number we count by on the x-axis
X-intercept: The point where the graph crosses/touches the x-axis
What's the output, f(x), when the input is 3?
f(3)=0 which means when the input is 3, the output is 0. We know this because (3,0) is a point on this graphed function.
What is f(6)?
f(6) = -2
What are all the input values?
-5 ≤ x < 6 which means all values greater than or equal to -5 AND less than 6 are input values. Note that -5 can be an input, but -6 cannot.
What is x when f(x) = 5?
x = -1 and 1
What are the two most common function names in the English language?
Function F and Function G
What is f(-6)?
f(-6) = 3 which means when the input is -6, the output is 3. We know this because (-6,3) is a point on this graphed function.
What is x when h(x) = 3?
x = 1
x = 2
What are all the output values?
y ≤ -6 which means the output values are all less than -6 or equal to -6.
