Answer:

X = 5

Step-by-step explanation:

-7x + 18 = -2x + 63

Cobine like terms by adding 7x to both sides and subtracting 63 from both sides:

18 - 63 = -2x - 7x

Simplify:

-45 = -9x

Divide both sides by -9

5 = x

The function y=ex is vertically stretched by a factor of 2, reflected across the x-axis, and then shifted down 3 units, find the

Anettt [7]

Answer:

$y = - 2 e^{x} - 3$

Step-by-step explanation:

We have to vertically stretch the function $y = e^{x}$ by a factor of 2.

Then the function will become $y = 2e^{x}$ .

Then it is reflected across the x-axis.

So, the new function will be $y = - 2e^{x}$ .

Now, if the function is shifted down 3 units then the final function will become $y = - 2 e^{x} - 3$ (Answer)
