If we change the equation for the quadratic function form y=2x^2+3x-5 to y= -2x^2+3x-5 describe what changes in the graph.

1 answer:

6 0

First convert them to vertex form

first one is y = 2(x + 0.75)^2 - 6.125

2nd is y = -2(x - 0.75)^2 - 3.875

the -2 will cause a reflection of the first equation in the x axis . then a translation down of 6.125 + 3.875 = 10 units , followed by
a translation of -0.75-0.75 = -1.5 units to the right = 1.5

Angle one equals 85 because when an angle is a complement of another angle that means their degrees added together equal to 90 degrees. And so you just do 90-5=85 to get your answer.
