(a) Find the slope m of the tangent to the curve y = 71 x at the point where x = a > 0. (b) Find equations of the tangent lines at the points (1,7) and (4, 7/2)
y(x) =
(at the point (1,7)
y(x) =
at the point (4, 5)

You are studying different function tools and begin working with this function y=-160-9(x) use the equation to answer the question y=-160-9(x) what is the y value when x equals -13? y=-160-9(x)
