Create a unique parabola in the pattern f(x)=(x-a)(x-b). Pick integers other than one or zero for a and b. let a= 1 and b= 2 f(x)= (x-1)(x-2) = x²-2x-x+2 = x²-3x+2 (this is the one I have made and just need help with the other parts) Describe the direction of the parabola. (Hint: How can you tell if a parabola will open upwards or downwards) Determine the y-intercept. (Hint: Using your equation, set the x’s equal to zero and solve for y) Determine the zeros. (Hint: Using your equation, set y = zero, factor, and solve for x.

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size.it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
