Consider the curve given by the equation 2x2−12x+y3=107. It can be shown that dxdy=3y24(3−x).Find the point on the curve where the line tangent to the curve is horizontal. (□ , □)
Q. Consider the curve given by the equation 2x2−12x+y3=107. It can be shown that dxdy=3y24(3−x).Find the point on the curve where the line tangent to the curve is horizontal. (□ , □)
Solve for x: Solve for x:4(3−x)=012−4x=04x=12x=3
Find y-coordinate: Now that we have the x-coordinate, we need to find the corresponding y-coordinate on the curve. We plug x=3 into the original equation of the curve to find y.2x2−12x+y3=1072(3)2−12(3)+y3=107
Calculate y3: Calculate the value of y3:2(9)−36+y3=10718−36+y3=107y3=107+36−18y3=125
Find y: Find the cube root of 125 to get y:y=125(1/3)y=5
