Explanation:step one: find the derivative of the equation. Step two: Since a horizontal line has a slope of 0, set the derivative to equal 0 and solve. Step three: plug the x-values found in step 2 back into the original equation to get the y-coordinates of the points on the curve.
#y(-2)= 21# Step four: write out the coordinates of the points with a slope of zero. Consider the following line. graph{y = 0x + 1 [-10, 10, -5, 5]} What can we say about this line? We can say that it is horizontal. Let's look at the slope. #m = (y_2 - y_1)/(x_2 - x_1) = (1 - 1)/(0 - 5) = 0/-5 = 0# The slope is #0#. So, the slope of any horizontal line is #0#, since any other horizontal line will be parallel to this one. Hence, we need to find the points on the derivative where the slope of the tangent is #0#. The derivative can be found using a combination of the sum/difference and power rules. #y' = 6x^2 + 6x - 12# The slope of the tangent is given by plugging in a point, #x = a#, into the derivative. Hence, we can set #y'#, the slope, to #0# and solve for #x#. #0 = 6x^2 + 6x - 12# #0 = 6(x^2 + x - 2)# #0 = (x + 2)(x - 1)# #x = -2 and 1# All that is left to do is determine the corresponding y-coordinates that the function passes through. #y = 2(-2)^3 + 3(-2)^2 - 12(-2) + 1 = 2(-8) + 3(4) + 24 + 1 = 21# AND #y = 2(1)^3 + 3(1)^2 - 12(1) + 1 = 2 + 3 - 12 + 1 = -6# Hence, the points where the tangent is horizontal are #(-2, 21)# and #(1, -6)#.
