How can you restrict the domain of the function f(x)=|x+4|-2 so the range of the inverse function f^-1(x),is [-4, )

1 answer:

5 0

The range of the inverse has to match the domain of the original function. We want to have $f^{-1}(x)$ map to $[-4,\infty)$ , so we restrict the domain of $f(x)$ to this interval.

Solve -5 + w divided by 3 = -1. 12 -12 2 -2

son4ous [18]

Hello!

Answer:

w=12

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

$-5+\frac{w}{3}+5=-1+5$

Then, you simplify.

$\frac{w}{3}=4$

Next, you multiply by 3 from both sides of an equation.

$\frac{3w}{3}=4*3$

And finally, simplify and solve. You can also multiply by the numbers from left too right.

$4*3=12$

Final answer: → $w=12$

Hope this helps!

Thanks!

what is the equation of a line that passes through the point (6,1) and is perpendicular to the line whose equation is y=2x-6?

alexandr402 [8]

Answer:

y = -(1/2)x + 4

Step-by-step explanation:

Use the standard form on an equation: y = mx + b

A line that is perpendicular has a slope that is the opposite reciprocal of the other line. We also have a point (x, y) that is on the line, so our equation begins as..

1 = -(1/2)(6) + b We must solve for b ( -1/2 is the opposite reciprocal of 2)

1 = -3 + b

4 = b

so our equation is

y = -(1/2)x + 4
