The curve produced by the water coming from a fountain is sketched on the graph. which function does the graph represent? f(x) = (x – 2)2 + 3 f(x) = –(x – 2)2 + 3 f(x) = (x + 2)2 + 3 f(x) = –(x + 2)2 + 3

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
