• Dependent Value
• Y-Value

Is this graph a function or not a function? 

• Function 
• Not a Function

Given f(x) =
2x² + 5x - 17, find f(-1). 

• f(-1) = -20
• f(-1) = -24

Which expression represents g(f(x)) if 
f(x) = 2x - 8 and
g(x) = 4x

• 8x - 32
• 8x² - 32x
• 8x - 8
• 6x - 8

f(x) = 3x + 10
g(x) = x - 2
Find g(f(-10))

• -42
• -26
• -18
• None of these.

What is the domain of the graph?

• y≥1
• x ≥ 1
• All real numbers
• none of these

• Even Function

• Odd Function

• Function - neither even nor odd

• Not a function

• Even Function

• Odd Function

• Function - neither even nor odd
