Use logarithmic differentiation to find the derivative of the function. y = x2cos x part 1 of 4 using properties of logarithms, we can rewrite ln y = ln(x2cos x) as

ANSWER

EXPLANATION

The given function is

We take natural log of both sides;

Recall and use the product rule of logarithms.

This implies that:

We now differentiate implicitly to obtain;

Multiply through by y,

Substitute y=x²cosx to obtain;

Expand:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the answer is c)8
