If f(x) = 2x+1/x-4 what is the value of f^-1(3)
Olegator [25]

Answer:

f^-1(3) = 1.719 or  f^-1(3) = 0.149

Step-by-step explanation:

for inverse function x and y coordinates are flipping so graph the function and find for what x - coordinate y- coordinate = 3

in case that f(x) = 2x + \frac{1}{x-4} than f^-1(3) = 1.719

in case that f(x) = 2x + \frac{1}{x} -4 than f^-1(3) = 0.149

Which interval is the solution set to 0.35x – 4.8 &lt; 5.2 – 0.9x?
Allushta [10]
No intervals are showing, but here is how to solve this equation.

0.35x - 4.8 < 5.2 - 0.9x
Add 4.8 to both sides
0.35x < 10 - 0.9x
add 0.9x to both sides
1.25x < 10
divide both sides by 1.25
x < 8

Interval Notation:
If we graphed this on a number line, x goes toward negative infinity.

Answer: (-∞, 8)

Hope this helps! :)
