for the function, find the points on the graph at which the tangent line is horizontal.\n\n( y = x ^ { 2 } - 6 )\n\na. the point(s) at which the tangent line is horizontal is(are) (type an ordered pair. use a comma to separate answers as needed.)\nb. the tangent line is horizontal at all points of the graph.\nc. there are no points on the graph where the tangent line is horizontal.
Answer
Explanation:
Step1: Find the derivative of the function
The derivative of (y = x^{2}-6) using the power rule ((x^{n})^\prime=nx^{n - 1}) is (y^\prime=\frac{d}{dx}(x^{2}-6)=2x).
Step2: Set the derivative equal to zero
Since the slope of a horizontal tangent line is (0), we set (y^\prime = 0). So, (2x=0).
Step3: Solve for (x)
Dividing both sides of (2x = 0) by (2), we get (x = 0).
Step4: Find the corresponding (y)-value
Substitute (x = 0) into the original function (y=x^{2}-6). Then (y=(0)^{2}-6=-6).
Answer:
A. The point(s) at which the tangent line is horizontal is(are) ((0,-6))
