Question

O GRAPHS AND FUNCTIONSFinding inputs and outputs of a function from its graph

Answer 1

Part A

f(x)=-4

Looking a the graph

we have that

For x=-1 --------> f(x)=-4

so

One value of x for which f(x)=-4 is -1

Part B

Find out f(1)

Remember that

f(1) is the value of f(x) when the value of x=1

so

Looking at the graph

For x=1 ---------> f(x)=2

therefore

f(1)=2
