Answer:

D. (f + g )( x ) = 6x³ - 3x² + 7x - 8

Step-by-step explanation:

<u>Given :-</u>

  • f ( x ) = 4x² + 7x - 3.
  • g ( x ) = 6x³ - 7x² - 5.

<u>To Find :-</u>

  • ( f + g ) ( x ).

<u>Solution :-</u>

(f + g )( x ) = 4x² + 7x - 3 + 6x³ - 7x² - 5.

Arranging like terms.

(f + g )( x ) = 6x³ - 7x² + 4x² + 7x -5 - 3

Combine like terms.

(f + g )( x ) = 6x³ - 3x² + 7x - 8

If f(x) = 2x2 +5/(x-2), complete the following statement:
faust18 [17]

For this case we have the following function:

f (x) = 2x ^ 2 + \frac {5} {x-2}

By definition, we have that the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero.

So:

x-2 = 0\\x = 2

Thus, the function is not defined at x = 2.

The domain is given by all real numbers except 2.

Answer:

The domain is given by all real numbers except 2.

What is the value of x?<br> (9x - 3)<br> (6x)<br> 48°<br> Enter your answer in the box.<br> X=
Dima020 [189]

Answer:  x = 9

Step-by-step explanation:

The sum of three interior angles of a triangle is 180°.

(9x - 3)  + (6x)  + 48° = 180°

9x - 3 + 6x + 48 = 180

15x + 45 = 180

15x = 135

x = 9
