Question

The graph of f(x) shown below resembles the graph of g(x)=2 but it has been changed her mind which of the following could be the equation of f(x)

Answer 1

A

Explanation:

cuz if you pay attention to the y coordinate on f(x) it's 4 instead of 1 as in g(x). this means that y-coordinate is multiplied to 4 therefore 4g(x) and it is vertically shifted up 1 unit and therefore the equation would be

f(x) = 4g(x) + 1

as g(x) = x²

.:

f(x) = 4x² + 1
