Which function has a vertex at the origin?
Crank

Answer:

B) f(x)=x(x-4)

Step-by-step explanation:

To find the function which has vertex at the origin.

Solution:

For a function to have its vertex at origin the function must pass through point (0,0) which means f(0)=0.

We will find f(0) for each of the given functions and check if it has vertex at origin.

To find f(0) we will plugin x=0 in the function.

A) f(x)=x+4

f(0)=0+4=4

Vertex is  not at the origin.

B) f(x)=x(x-4)

f(0)=0(0-4)=0  [Any number times zero is = zero]

Vertex is at the origin.

C) f(x)=(x-4)(x+4)

f(0)=(0-4)(0+4)=(-4)(4)=-16

Vertex is  not at the origin.

D) f(x)=2

f(0)=2

Vertex is  not at the origin.
