Answer:

f(g(x)) =  x² - 5x +4

Step-by-step explanation:

<u><em>Explanation</em></u>

Given that the functions

         f(x) = x² + 3 x   and g(x) = x-4

     f(g(x)) = f(x -4)   (∵ g(x) = x-4)

              = (x-4)² + 3(x-4)

              = x² - 2(4)x + 4² + 3x -12

             = x² - 8 x + 16 + 3x -12

             = x² - 5x +4

∴ f(g(x)) =  x² - 5x +4

The distance between (-5, 3) and B(5, 3) is
8090 [49]
In here, we will use the distance formula
\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

Compute the distance between <span>(-5, 3) and (5, 3)
</span>=\sqrt{\left(5-\left(-5\right)\right)^2+\left(3-3\right)^2}
<span>
= 10 

The distance between </span>(-5, 3) and (5, 3) is 10
