What is the quadratic regression equation for the data set? (see chart) yˆ=0.032x2−0.601x yˆ=0.032x2−0.601 yˆ=0.032x2+0.601x−0.255 yˆ=0.032x2−0.601x−0.255

Is this a polynomial function? i need to know asap

Which function has the domain x> -11?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
