What is the slope of the line x = 4?

Undefined

Step-by-step explanation: Since there is no change in x, and it is a horizontal line, that means that the denominator is zero. Dividing anything with the denominator being 0 will always be undefined (Not to be confused with the numerator, which is just dividing by 0, thus giving you 0.) That means that our answer will be undefined.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2
