Answer:
First Picture Answer:
x=0, x=2/3 are extraneous Solutions
Second Picture Answer:
(-infinity, -3)(-3, infinity)
Third Picture Answer:
x=3
Fourth Picture Answer:
x=0, x=2 is extraneous solution
Fifth Picture Answer:
x=3/2 is the vertical asymptote
Step-by-step explanation:
First Picture Answer:
x/4=x^2/x+2
Multiply each side with 4(x+2)
x(x+2)=4x^2
x^2+2x-4x^2=0
-3x^2+2x=0
Taking x Common
x(-3x+2)=0
x=0, -3x+2=0
x=0, x=2/3
Second Picture Answer:
f(x)=x-1/x+3
A rational function is simply a fraction and in a fraction the denominator cannot be equal zero because it would be undefined. To find which numbers make the fraction undefined, create an equation where the denominator is not equal to zero.
x+3 is not equal to 0
x is not equal to -3
so our domain is (-infinity, -3)(-3, infinity)
Third Picture Answer:
3x-5/7=4/7
Multiply with 7 on both sides
3x-5=4
3x-=9
x=9/3
x=3
Fourth Picture Answer:
4x^2=(3x^2+2)x
4x^2=3x^2+2x
4x^2-3x^2-2x=0
x^2-2x=0
x(x-2)=0
x=0, x-2=0
x=0, x=2
Fifth Picture Answer:
Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. Set the denominator of the above fraction equal to zero and solve, this will tell the values that x can not be:
2x-3=0
x=3/2
so x cannot be 3/2 which is the vertical asymptote

The domain of a function f (x) is the set of all input values x, for which the function is defined.
For example, for the function
, its domain is all real numbers except the one that makes 0 the denominator of the expression, since the division between 0 is not defined. The value that makes the denominator zero ex x = 1. Then the domain of the function is the set of all real numbers minus the {1}
In this case , the function f (x), which is a polynomial function, is defined for the set of all real numbers, that is, its domain is all the real numbers.
The range of a function is the set of all possible dependent values that the function can produce. In other words, it is the set of all possible outputs of the function.
For the case of the function , its range, as well as its domain, covers all real numbers.
