Answer:

y=\frac{-x^{3}}{125}

Step-by-step explanation:

As we know that,

<em>'Horizontal stretch, stretches the function left or right on the x-axis'. </em>

The general form of horizontal stretch is given by 'f(kx)', where 0<k<1 is the factor by which function is stretched horizontally.

Since, the function y=x^{3} which is stretched by a factor of \frac{1}{5}.

The new function is y=(\frac{x}{5})^{3} i.e. y=\frac{x^{3}}{125}.

<em>Further, the function is reflected over y-axis.</em>

That is, the reflected function is y=\frac{(-x)^{3}}{125} i.e. y=\frac{-x^{3}}{125}.

Hence, the required function is y=\frac{-x^{3}}{125}.

Answer:

  \dfrac{2x}{3a^2}

Step-by-step explanation:

\dfrac{3a^4b}{2x}\cdot\dfrac{4x^2}{9a^6b}=\dfrac{3\cdot 4}{2\cdot 9}a^{4-6}b^{1-1}x^{2-1}=\dfrac{2x}{3a^2}

The applicable rules of exponents are ...

  • (a^b)(a^c) = a^(b+c)
  • a^-b = 1/a^b
