Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y.

Plz help me with this

Answer:

$(x,y) = (-1,-2.5)$

Step-by-step explanation:

Let be $f(x) = \frac{(x+3)^{2}}{x-2}$ and $g(x) = \left|\frac{x}{2}\right| -3$ , we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when $f(x) = g(x)$ . Graphically speaking, it means that a solution exists when both curves pass through each other.

According to the graphic tool, we conclude that the only solution to the system of equations is $(x,y) = (-1,-2.5)$ .

What is the solution to 2(x - 3) = 2x + 5

laila [671]

Answer:

X cannot be decided

Step-by-step explanation:

According to the question,we will start solving the problem by dealing with the bracket first

So let's get to work

2(x-3)=2x+5

Bracket first

2x-6=2x+5

So let's collect like terms

2x-2x=5+6

0=11

Which means the that we can't get the value for x because x has already been eliminated

So to my own understanding there is no definite solution to get the real value of x

I hope you understand
