Question

Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = -3x2 - 36x - 60?

Answer 1

Answer:

A) The graph of f(x) = x2 is made narrower.

Step-by-step explanation:

The transformed graph has equation:

$g(x) = - 3 {x}^{2} - 36x - 60$

To see the transformations clearly, we need to rewrite the function in the vertex form:

$g(x) = - 3( {x}^{2} + 12x) - 60$

$g(x) = - 3( {x}^{2} + 12x + 36) - 60 + 3 \times 36$

$g(x) = - 3( {x} + 6)^{2} + 48$

Therefore, the graph of the original function is made narrow of the multplier, 3.

The correct answer is A
