Question

If you vertically stretch the absolute value parent function, f(x) = |x|, by a factor of 3, which of these is the equation of the new function?

A. g(x) = |x – 3|

B. g(x) = |x|

C. g(x) = 3|x|

D. g(x) = |x + 3|

Answer 1

The answer is C because 3|x| will be a taller, narrower version of |x|

Hope this helps
