For `f(x)=3x^(2)+4,g(x)=2, and h={(1,1),(2,1),(3,2)}`

A

f is the only function

B

h is the only function

C

f and g are the only functions

D

f, g, and h are all functions

Text Solution

Verified by Experts

The correct Answer is:
D
For each value of x there is only one value for y in each case. Therefore, f,g, and h are all functions.
