Determine the domain of the function.

Dafna1 [17]

We are given with a verbal phrase of a function of x is equal to the square root of x plus one divided by x plus four times x minus six.

This is expressed as f(x) = √(x) + 1/x + 4x - 6
the domain are values which include only natural numbers because of the square root sign. answer is D. x ≥ 0

For the equation given below, evaluate y′ at the point (−2,2) xe^y−4y=2x−4−2e^2

jeka94

Implicit differentiation
chain rule is important here

I'll show the steps partially
$e^y+xe^yy'-4y'=2$
$xe^yy'-4y'=2-e^y$
$y'(xe^y-4)=2-e^y$
$y'=\dfrac{2-e^y}{xe^y-4}$
now evaluate for (-2,2)
x=-2 and y=2
$y'=\dfrac{2-e^2}{-2e^2-4}$
$y'=\dfrac{2-e^2}{-2e^2-4}$
$y'=\dfrac{e^2-2}{2e^2+4}$
that's it, simplest form

Factor completely 7x²-9x-10

Shtirlitz [24]

Answer:

First, assign a value to x. x will be 2 in this case.

Next, multiply x by itself, because that is what exponent 2, or squared, means. 2 x 2 = 4

Now, multiply 4 by 7. 4 x 7 = 28

Next, find the value of 9x.

The value of 9x will be 9 times a number, x, also known as 2 in this scenario. 9 x 2 = 18

Then, subtract 28 from 18. 28 - 18 = 10

Lastly, subtract 10. 10 - 10 = 0
