I’m bored who wants to talkzzz

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
