1. Find an exponential equation that passes through the points (2, 2.25) and (5,60.75). 2. Find an exponential equation that passes through the points (0,4) and (2,9).

3. Determine whether the function y = 156(0.825)' represents exponential growth, exponential decay, or
neither. Explain
4. The graph of f(x)=6.5x is reflected about the y-axis and stretched vertically by a factor of 7. What is the
equation of the new function, g(x)?

y=mx+b is the final answer!   : )

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

1010: 3030

is it i think
