Question

F(x) = x2. What is g(x)?

g(x)
5
-(1,4)
f(x)
X
-5
5
-5

Answer 1

B. g(x) = 4x²

Explanation:

f(x)= x²

the shape of f (x ) and g( x ) is same.

and those graphs lower point is ( 0 , 0 )

therefore,

will, g(x) = kx² (k ∈ real numbers)

the g(x) graph goin through the point ( 1 , 4 )

therefore,

4 = k × 1²

k = 4

∴ g(x) = 4x²
