If you vertically stretch the exponential function f(x)=2^x by a factor of 3, what is the equation of the new function

AleksAgata [21]

Answer:

$y=3*2^{x}$

Step-by-step explanation:

A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form

$y=ab^{2}$ .

If our equation is $f(x)=2^x$ , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.

$y=3*2^{x}$

Fine the following when a=-2, b=4, c=7<br> 7b-12 over 2ac

iren [92.7K]

Hello!

You have to put the numbers in for the variables in the equation

$\frac{7b - 12}{2ac}$

Put the numbers in

$\frac{7(4) - 12}{4(-2)(7)}$

Combine like terms

$\frac{28 - 12}{-56}$

$\frac{16}{-56}$

The is is $\frac{16}{-56}$ or about -0.29

Hope this help!
