SOLUTION We will be able to find an equation of the tangent line t soon as we know its slope m. The difficulty is that we know only one point, P, on t, whereas we need two points to compute the slope. Bu observe that we can compute an approximation to m by choosing a nearby point Q(x, 4x?) on the graph (as in the figure) and computin slope mpo of the secant line PQ. [A secant line, from the...

Find the slope of the line tangent to f(x) at x = 3. The graph of f(x) is shown below. Move the point on the curve to x = 3. Then plot two points on the tangent line. Finally, calculate the slope of the tangent line at x = 3. Answer 2 Points Keypad Points can be moved by dragging or using the arrow keys. Any lines or curves will be drawn once all required points are plotted and will...
5. (10 points) Let f(x) = -(9x² +6x+2). Then according to the definition of derivative f'(x) = lim h0 (Your answer above and the next few answers below will involve the variables x and h. We are using h instead of Ar because it is easier to type) We can cancel the common factor — from the numerator and denominator leaving the polynomial Taking the limit of this expression gives us f'(x) = 6.
