Answer:

x+9

Step-by-step explanation:

4x³+12x²-72x

=4x(x²+3x-18)

=4x[x²+6x-3x-18]

=4x[x(x+6)-3(x+6)]

=4x(x+6)(x-3)

Answer:

y = $-2^x$

Step-by-step explanation:

If the equation of a function is in the form of y = h(x)

When the graph of this function is reflected across x-axis,

Transformed function will be,

y = -h(x)

Further reflected across y-axis, then the transformed function will be,

y = -h(-x)

By this rule,

Given equation when reflected across x-axis,

y = $-(\frac{1}{2})^{x}$

Further reflected across y-axis,

y = $-(\frac{1}{2})^{-x}$

y = $-(2^{-1})^x$

y = $-2^x$
