F(x) = 3x + 21; solve for f(3) and f(7)

Inessa [10]

Answer:

Step-by-step explanation:

Given that f(x) = 3x + 21

Plug in 3 for x

F(3)= 3(3) +21

F(3) = 9+21

f(3) = 30

Plug in 7 for x

F(7)= 3(7) +21

F(7) = 21+21

f(7) = 42

Simplify the question above

andrey2020 [161]

Answer:

$1 + \frac{3}{x}$

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

$\frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x}$

2) use difference of squares: a² - b² = ( a + b ) (a - b).

$\frac{(x + 3)(x - 3)}{ {x}^{2} - 3x}$

3) Factor out the common term x.

$\frac{(x + 3)(x - 3)}{ x(x - 3)}$

4) Cancle out x - 3 .

$\frac{x + 3}{x}$

5) Simplify.

$1 + \frac{3}{x}$

Therefor, the answer is 1 + 3/x.
