Suppose that the functions p and q are defined as follows. p(x) = 2x+1
g(x) = -x² - 1
Find the following.
(p•q)(1) =
(q•p) (1) =

Simply 8x squared + 5(7x squared- x) - 2x =

Someone answer this check out the image!

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
