Answer:

Step-by-step explanation:

We have the expression 3(x - 2) and we also know the value of x which is 2.

To solve for this, we need to substitute x with the value given :

3(x - 2) when x = 2

3(2 - 2)

Now follow PEMDAS and do the equation within the parenthesis.

2 - 2

3(0)

Now multiply 3 and 0 :

3 * 0

Given f(x) = 2x + 6, and g(x) = x2 + 6, find (g ○ f)(1).

Kryger [21]

$\bf \begin{cases} f(x)=2x+6\\ g(x)=x^2+6\\ (g\circ f)(x)\implies g(~~f(x)~~) \end{cases} \\\\[-0.35em] ~\dotfill\\\\ f(1)=2(1)+6\implies f(1)=\boxed{8} \\\\[-0.35em] ~\dotfill\\\\ g(~~f(1)~~)\implies g\left(\boxed{8} \right)=(8)^2+6\implies g(8)=64+6\implies \stackrel{g(~~f(1)~~)}{g(8)}=70$

Answer:

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10} = \frac{7x - 10}{5}, x \neq -2$

Removable (Holes)
Jump (Piece-wise functions)
Infinite (Asymptotes)

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10}$

Step 2: Simplify

[Frac - Numerator] Factor quadratic: $\displaystyle \frac{(7x - 10)(x + 2)}{5x + 10}$
[Frac - Denominator] Factor GCF: $\displaystyle \frac{(7x - 10)(x + 2)}{5(x + 2)}$
[Frac] Divide/Simplify: $\displaystyle \frac{(7x - 10)}{5}, x \neq -2$

When we divide (x + 2), we would have a removable discontinuity. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.
