For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:
16 ---------------> 100%
4 -----------------> x
Where "x" represents the% of painters who paint the interior of the house.
Thus, 25% of painters are painting the interior of the house.
Answer:
25%
The function has an inverse that is also a function is g(x) = 2x – 3.
The correct option is A.
We have to determine
Which function has an inverse that is also a function?
<h3>Inverse function;</h3>The inverse of a function is the equation where x and y have switched places.
If when you solve for y again, the function passes the vertical line test, the inverse if a function.
1. Here g(x) = 2x - 3 has inverse x = 2y - 3 which simplifies to;
This is a line and is a function;
2. k(x) = -9x^2 has the inverse x = -9y^2 which simplifies to;
This is a function but only for certain values of x.
3. f(x) = |x+2| is an absolute value function.
All absolute value functions do not have inverses which are functions.
4. w(x) = -20 does not have an inverse which is a function.
Hence, the function has an inverse that is also a function is g(x) = 2x – 3.
