Answer:
(0,1) and (-2,9)
Step-by-step explanation:
A point (x,y) lies on the graph of f(x) = if it satisfies the condition y =
x = 0 and y = 1.
This point satisfies the required condition as
= 1
Hence, this point <u>is</u> on the graph of f(x) =
x = 3 and y = 27.
This point doesn't satisfy the required condition as
=
≠ 27
Hence, this point i<u>s not</u> on the graph of f(x) =
x = -2 and y = 9.
This point satisfies the required condition as
=
= 9
Hence, this point <u>is</u> on the graph of f(x) =
x = -1 and y = .
This point satisfies the required condition as
y = =
= 3 ≠
Hence, this point <u>is not</u> on the graph of f(x) =
