Numerical Answers Expected!

Answer 1

Here the co-ordinates are

• (-3,0)
• (-2,2)
• (0,1)
• (1,-2)

If (x,y) is a cordinate pair then x is domain and y is range

So

• f(0)=1

Answer 2

1

Explanation:

f(0) means that 0 is the input value for the function, i.e. x = 0

By inspection of the graph, the value of y when x = 0 is y = 1

Therefore, f(0) = 1
