hmu if ur willing to do a algebra a online class i’ll pay 600 hmu on the gram profitpreme

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
