This is what she/he is saying:

A stone is thrown into a pool of calm water which creates concentric waves that increase the radius over time. When the external wave reaches a radius of 3 meters, it increases at a speed of 5 cm / s, at what speed does this area of ​​the circle increase by said wave?

Consider parent function f(x)=e^x and the transformes function g(x)= -1/2e^3x+4, quantitatively explain the transformations to t
kolezko [41]

Answer:  reflection across the x-axis

               vertical shrink by a factor of 1/2

               horizontal shrink by a factor of 1/3

               vertical shift up 4 units      

<u>Step-by-step explanation:</u>

\text{Note:}\ g(x) = -Ae^{Bx-C}+D\\\bullet \quad \text{- represents a reflection across the x-axis}\\\\\bullet \quad \text{A represent a vertical stretch by a factor of A (shrink if}\ |A| < 1)\\\\\bullet \quad \text{B represents a horizontal stretch by a factor of}\ \dfrac{1}{B}\ (\text{shrink if}\ |B| >1)  \\\\\bullet \quad \text{C represents a horizontal shift of C units}\ (\text{+ is right, - is left}) \\\\\bullet \quad \text{D represents a vertical shift of D units}\ (\text{+ is up, - is down})

\text{Parent function:}\ f(x)=e^x\\\text{Transformed function:}\ g(x)=-\dfrac{1}{2}e^{3x}+4\\

The transformed function has the following:

Negative:    reflection across the x-axis

A = 1/2         vertical shrink by a factor of 1/2

B = 3            horizontal shrink by a factor of 1/3

C = 0            no horizontal shift

D = 4            vertical shift of 4 units up
