The function g(x) = 2x2 – 28x + 3 written in vertex form is g(x) = 2(x – 7)2 – 95. Which is one of the transformations applied to the graph of f(x) = x2 to produce the graph of g(x) = 2x2 – 28x + 3?

1)shifted up 3 units

2)shifted left 7 units

3)shifted right 7 units

4)shifted down 3 units

Verified Answer :

3)shifted right 7 units

Answer

3)shifted right 7 units

Explanation

Remember the translation rules:

\(f(x)+b\) shifts the function b units upward

\(f(x)-b\) shifts the function b units upward

\(f(x+b)\) shifts the function b units to the left

\(f(x-b)\) shifts the function b units to the right

From the vertex form: \(g(x)=2(x-7)^2-92\),of our function, we can infer that:

The parent function \(f(x)\) has been shifted 7 units to the right (look at the term \((x-7)^2\)) and 91 units upward.

So we can conclude that the correct option is: 3)shifted right 7 units
