the graph shows two functions, f(x) and g(x). if the functions are combined so that h(x) = f(x) - g(x), then the domain of the f
Sergio039 [100]

The domain of the function h(x) is x is greater than​ -1

<h3>How to determine the domain of the function h(x)?</h3>

The graphs of the functions are given as attachment

From the attachment, we have the following domains:

  • Domain of f(x): x > 2
  • Domain of g(x): x > -1

The equation of function h(x) is

h(x) = f(x) - g(x)

The domain of the function g(x) is greater than that of the function f(x)

This means that the function h(x) will assume that domain of the function g(x)

Hence, the domain of the function h(x) is x is greater than​ -1

Simplify the rational expression. state any excluded values. <br><br> x^2-3x-10/x+2
Natali5045456 [20]

Answer:

The answer to your question is  x - 5 or x = 5

Step-by-step explanation:

                                           \frac{x^{2} -3x - 10}{x + 2}

1.- Factor the numerator

                                       x² - 3x - 10

    find 2 numbers that added equal -3 and multiply equal -10.

    These numbers are -5 and + 2

                                     (x - 5)(x + 2)

2.- Simplify

                                     \frac{(x - 5)(x + 2)}{x + 2)}

Delete (x +2) in both numerator and denominator

3.- Result                       x - 5

                                      x = 5
