General form for vertex form is:
y = a(x - h)² + k
Where the vertex is the point (h, k). We know this to be (5, -3), so we can substitute the values for h and k to get:
y = a(x - 5)² - 3
We then also have another point (6, 1) that gives us an x and y. Substitute those in to leave one unknown which we can solve for:
1 = a(6 - 5)² - 3
1 = a(1)² - 3
1 = a(1) - 3
1 = a - 3
4 = a
So the equation of this parabola in vertex form is:
y = 4(x - 5)² - 3

PART A
write two different, equivalent expressions for how much the rosebush will cost if the coupon is applied first and the 10% discount second. <em><u>d-(d-5)</u></em><em><u>.</u></em><em><u>10</u></em><em> </em>= 27.5 <em>(if you put d in as 30!)</em>
PART B
write an expression for how much the rosebush will cost if the 10% discount is applied first and the coupon is applied second. <em><u>d-(d*.10)-5</u></em><em> </em><em> </em>=22 <em>(if you put d in as 30!)</em>
PART C
which order will save marina more money? explain your reasoning.
<u>d-(d*.10)-5</u><u> </u>This equals less! if you put in 30 as an example
So, A) <u>d-(d-5).10 </u>B)<u> </u><u>d-(d*.10)-5</u><u> </u>C) <u>d-(d*.10)-5</u>
One batch = 1/4
One whole cup is 4 batches
3/4 a cup is 3 batches
If you add together one and 3/4 you get 7 Batches
