Draw a quadratic function below with zeros at -3 and 5 that is also concave up.

Hello from MrBillDoesMath!

x^2 - 2 x - 15

Discussion:

( x - (-3)) * ( x- 5) =

(x +3) (x-5) =

x^2 - 2 x - 15

It is a concave upward curve (looks like a "u") as the x^2 term causes the function to grow larger as x approaches +\- infinity.

Thank you,

MrB

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
