Let g(x) = 7X2 - 6 (a) Find the average rate of change from 8 to 3- (b) Find an equation of the secant Iine containing ( ~ 8, 9( 8)) and (3, 9(3)).
(a) The average rate of change from #8 to 3 is
(Simplify your answer )
(b) An equation of the secant Iine containing ( ~ 8, 9( ~ 8)) and (3, 9(3)) is (Type your answer in slope-intercept form )
