What is the domain of the function y = -4x+1 if the range is -11
a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

y=-4x+1

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

x=-\frac{1}{4}(y-1)

If the range of the original function is the set given by the number {

6x²-13x=-6<br> Solve the equation using the quadratic formula
nalin [4]

Answer:

x=2/3, x=3/2

Step-by-step explanation:

6x^2-13x=-6

6x^2-13x+6=0

6x^2-4x-9x+6=0

2x*(3x-2)-3(3x-2)=0

(3x-2)8(2x-3)=0

3x-2=0

2x-3=0

x=2/3

x=3/2

2 over 8 divided by 1 over 2 =
Illusion [34]
Answer: 1 over 2 (1/2)

Simplify 2 over 8 to get 1 over 4. Now you have 1 over 4 divided by 1 over 2. Whenever you divide with fractions you flip the fraction and multiply . So it becomes 1 over 4 multiplied by 2 over 1.

2/8 (divided by) 1/2
1/4 (divided by) 1/2
1/4 x 2/1
= 1/2
