Question

Which equation describes how the parent function,
`y=x ^(3)`, 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

b

Explanation:

Answer 2

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)`
