Question

What function does this graph represent?

Answer 1

B.
`f(x)=0.2(x-2)^2+1`

Explanation:

The equation of a parabola in the vertex form is given by:

`f(x)=a(x-h)^2+k`, where V(h,k) is the vertex of the parabola

This parabola opens upwards and has its vertex at: V(2,1)

The a-value must therefore be positive.

The function must be

`f(x)=0.2(x-2)^2+1`

The correct option is B.
