Functions for ELL

Is this graph a function or not a function? 

• Function 

• Not a Function

Find f(2)

• 5

• 4

• 3

• 0

Find the missing  x-value:

• -14

• 14

• 4

• -4

Find the missing f(x) value:

• 10

• -2

• -1

• 2

f(-2)=​ (a)  

g(-2)=​ (b)  

h(-2)=​ (c)  

• 3

• 6

• -3

• -6

• 5

• -5

• 11

• -11

Compare the functions

g(0)=​ (a)   and h(0)=​ (b)  

so

g(0) ​ (c)   h(0)​

• 7

• 6

• >

• <

Evaluate the given function.

Mathematical Equivalence

ON

True or False: This set of ordered pairs represents a FUNCTION

• True

• False

Find the missing g(x) value:

• -1

• 1

• 0.0625

• -0.0625

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
