Pls help me with this. i have finals tomorrow and i dont get this

We're here to help! Let me take this slowly.

44. First, we have the x-coordinate of the vertex to be -b/2a which is 16. Plugging 16 in, we have y-coordinate to be 135.

Notice that it is y=(x-7)(x-1).

So, we can just plug in values for x and y. Once you've got a lot of points, you can connect the dots and see how you can graph it.

The axis of symmetry is the x-coordinate of the vertex, or x=16.

45. Do the same method as mentioned above. I personally think that using transformations are more confusing, but that's just opinion. The axis of symmetry is x=-(-4)/2(-1) = -2, so axis of symmetry is x=-2.

46. We have x=-4 or x = 1/2.

47. We have (y-7)(y-1) = 0 ==> y=7,y=1

48. We have w^2 = 9, so w = +/- 3

49. We have (p-10)(p-3)=0, so p=10, p=3

50. We have (3m+1)(m+3)=0, so m=-1/3, m=-3
