Q. Find the derivative of the following function.y=6−4x2Answer: y′=
Rewrite function: We are given the function y=6−4x2. To find the derivative, we will use the chain rule and the exponential rule for differentiation.
Apply chain rule: First, let's rewrite the function using the natural exponential function for convenience in differentiation:y=eln(6)⋅(−4x2)
Differentiate with ln(6): Now, let's differentiate both sides of the equation with respect to x using the chain rule:dxdy=dxd[eln(6)⋅(−4x2)]
Simplify exponent differentiation: Applying the chain rule, we get: dxdy=eln(6)⋅(−4x2)⋅dxd[ln(6)⋅(−4x2)]
Differentiate −4x2: Since ln(6) is a constant, we can simplify the differentiation of the exponent as follows:dxdy=eln(6)⋅(−4x2)⋅ln(6)⋅dxd[−4x2]
Substitute back derivative: Now, differentiate −4x2 with respect to x:dxd[−4x2]=−4×2x=−8x
Rewrite in terms of y: Substitute the derivative of −4x2 back into the equation:dxdy=e(ln(6)⋅(−4x2))⋅ln(6)⋅(−8x)
Substitute original y: Finally, we can rewrite the derivative in terms of the original function y:dxdy=y⋅ln(6)⋅(−8x)
Simplify final answer: Now, we can substitute back the original expression for y to get the final derivative: dxdy=6(−4x2)⋅ln(6)⋅(−8x)
Simplify final answer: Now, we can substitute back the original expression for y to get the final derivative: dxdy=6(−4x2)⋅ln(6)⋅(−8x)Simplify the expression to get the final answer: y′=−8x⋅ln(6)⋅6(−4x2)
