The functions g and h are given by g(x) = x + 1 and h(x) = x²
Delvig [45]

Answer:

x = - \frac{3}{2} , x = 2

Step-by-step explanation:

To find h(g(x)) substitute x = g(x) into h(x) , that is

h(g(x))

= h(x + 1)

= (x + 1)²

= x² + 2x + 1

For h(g(x)) = 3x² + x - 5 , then

3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides

2x² - x - 6 = 0 ← in standard form

(2x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - \frac{3}{2}

x - 2 = 0 ⇒ x = 2

dusya [7]

Answer:

\frac{1}{8} chance or 12.5% chance

2 female <em>percussionists</em>

3 male <em>woodwinds</em>

<u>2 </u><u>female</u><u> </u><u><em>woodwinds</em></u>

4 male <em>brass players</em>

3 female <em>brass players</em>

We're looking for a female <em>woodwind. </em>Now there is only 2 of them so we get the female woodwinds out of all the jazz band members or \frac{2}{16} or \frac{1}{8} or 12.5% chance.
