# Find the derivatives of the functions in Problems 1-34. y = e x 2 − 9

To determine

To calculate: The derivative of function, y=ex29.

Explanation

Given Information:

The function provided is y=2ex29.

Formula used:

According to the property of derivatives, if f(x)=cu(x), where, c is a constant and u(x) is a differentiable function of x, then,

f(x)=cu(x)

According to the property of derivatives, for a function, y=eu, where, u is a differentiable function of x,

dydx=eududx

According to the power rule, if y=xn, then,

dydx=nxn1

Calculation:

Consider the function,

y=ex29

Differentiate both sides with respect to x,

dydx=ddx(ex29)

Now apply the properties of derivatives ddxeu=eududx,

dydx=ex29(ddx(x29))=ex29
