In Exercises 47-52, find the indicated derivative. y = x 1.2 3 − x 0.9 2 ; d y d x

To determine

To calculate: The derivative dydx of function y=x1.23x0.92.

Explanation

Given Information:

The provided function is y=x1.23x0.92.

Formula used:

Sum rule of derivatives is ddx[f(x)+g(x)]=ddxf(x)+ddxg(x).

Constant multiple rule is ddx[cf(x)]=cddxf(x), where c is constant.

Power rule of a function y=xn is dydx=nxn1, where n is some constant.

Calculation:

Consider the function, y=x1.23x0.92.

Apply difference rule of derivative and differentiate with respect to x,

dydx=(x1.23x0.92)=ddx(x1
