Step3: Now that we have the slope of the tangent line and the point , we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is , where is a point on the line and is the slope of the line. Plugging in the values we have, we get . Simplifying this gives us the equation of the tangent line: .
Steps
Step 1 :Step1: First, we find the derivative of . The derivative of the function, denoted as or , gives us the slope of the tangent line to the curve at any point . Using the power rule for differentiation, we get .
Step 2 :Step2: Then, we plug into to find the slope of the tangent line at the point . We get . So, the slope of the tangent line is -3.
Step 3 :Step3: Now that we have the slope of the tangent line and the point , we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is , where is a point on the line and is the slope of the line. Plugging in the values we have, we get . Simplifying this gives us the equation of the tangent line: .
