Describe how the graph of the equation relates to the graph $$y = x ^ { 2 }$$
-$f ( x ) = 6 x ^ { 2 }$
A) a translation 6 units to the right
B) a horizontal stretch by a factor of 6
C) a translation 6 units up
D) a vertical stretch by a factor of 6

Question

Quizplus · Accepted Answer

The graph of $f(x) = 6x^2$ is a vertical stretch by a factor of 6 of the graph of $y = x^2$, because the coefficient 6 multiplies the $x^2$ term, affecting the y-values but not translating the graph horizontally or vertically.
