Question

Enter the letter for the function

graphed below.
a) y = x + 2
b) y = √x-2
c) y =
3
x-2+2
x + 2-2
d) y =
e) y = √x+2

Answer 1

a)y=∛(x+2)

Explanation:

The graph have domain: x∈R

That is mean b) and e) can't be solution to this graph.

(-2,0) belong to the function. x=-2 y=0

Check:

a)y=∛(x+2) x=-2 y=0

0=∛(-2+2)

0=∛0

0=0 correct

a) is the answer.
