Find the derivative of f(x) = 4x + 7 at x = 5.

4 or x=3

Step-by-step explanation:

The power rule is  

( d /d x )  x *n = n x *n − 1

I just used the power rule to solve

or

4x=5+7

Simplify  5+7  to  12

4x=12

Divide both sides by 4

x=12/4

Simplify 12/4 to 3

x=3

(Sorry if it wasn't what you were looking for)

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
