Let f left-parenthesis x right-parenthesis equals 2 x squared plus x minus 3 and g left-parenthesis x right-parenthesis equals x minus 1. Perform the indicated operation, then find the domain. left-parenthesis f minus g right-parenthesis left-parenthesis x right-parenthesis A. x squared minus 4; domain: positive real numbers B. 2 x squared minus 4; domain: all real numbers C. x squared minus 4; domain: all real numbers D. 2 x squared minus 2; domain: all real numbers

The value of (f-g)(x) is . Thus, the correct option is (D)

Two different functions are given that are as follow:

We need to determine the value of the composite function that is (f-g)(x).

Now, by using the property of the composite function (f-g)(x) can also be written as:

Substitute the values of both the functions and solve it further for (f-g)(x).

Thus, the value of (f-g)(x) is . Thus, the correct option is (D)

Step-by-step explanation:

Given that the functions f and g are defined by

and

To find (f-g)(x)

Substitute the values of the functions we get

( by adding the like terms )

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
