The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).

what is the equation of this parabola?

The answer is y=2x^2+8x-12

Step-by-step explanation:

(-5,-28)

i graphed to on desmos.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
