Question

Which equation describes how the parent function, e="y=x ^{3} " alt="y=x ^{3} " align="absmiddle" class="latex-formula">, is vertically stretched by a factor of 4?
A.) y=$y=x^{3}+4$
B.) $y=(x+4)^{3}$
C.) $y=4x^{3}$
D.) $y=x^{4}$

Answer 1

G(x) is vertically stretched of f(x) by a factor a if and only if  g(x)=a f(x) so
f(x)=$x^{3}$
g(x)=4$x^{3}$
