The graph of y=|x| is scaled vertically by a factor of (7)/(2). What is the equation of the new graph? Choose 1 answer: (A) y=-(2)/(7)|x| (B) y=-(7)/(2)|x| (c) y=(2)/(7)|x| (D) y=(7)/(2)|x|

Identify vertical scaling effect: : Identify the effect of vertical scaling on the function. When a function y = f(x) is scaled vertically by a factor of a, the new function becomes y = a * f(x). In this case, f(x) = |x| and the scaling factor is (7)/(2).Apply vertical scaling factor: : Apply the vertical scaling factor to the original function. The new function after scaling will be y = (7)/(2) * |x|.Match new function to choices: : Match the new function to the given choices. The new function y = (7)/(2) * |x| corresponds to choice (D) y=(7)/(2)|x|.

Identify vertical scaling effect: : Identify the effect of vertical scaling on the function. $\newline$ When a function $y = f(x)$ is scaled vertically by a factor of $a$ , the new function becomes $y = a \cdot f(x)$ . In this case, $f(x) = |x|$ and the scaling factor is $\frac{7}{2}$ .
Apply vertical scaling factor: : Apply the vertical scaling factor to the original function. $\newline$ The new function after scaling will be $y = \frac{7}{2} \cdot |x|$ .
Match new function to choices: : Match the new function to the given choices. $\newline$ The new function $y = \frac{7}{2} \cdot |x|$ corresponds to choice (D) $y=\frac{7}{2}|x|$ .
