Identify the oblique asymptote of f(x) = quantity 2 x squared plus 3 x plus 8 over quantity x plus 3.
3241004551 [841]
The oblique asymptote in the slope-intercept form is:
y = m x + b,  where:
m = \lim_{x \to \infty}  \frac{ 2x^{2}+3x+8}{ x^{2} +3x} = 2
b = \lim_{x \to \infty}  \frac{ x^{2} +3x+8}{x+3} - 2 x = \\  \lim_{x \to \infty}  \frac{2 x^{2} + 3 x + 8 - 2 x^{2} -6x}{x+3}= \\  \lim_{x \to \infty}  \frac{-3x+8}{x+3} = -3
Answer:  y = 2 x - 3

A function g(x) is an absolute value function that has been shifted 2 units to the right and 3 units down.
nata0808 [166]
The parent functuion is the absolute value funtion
f(x) =  |x|
f(x+c) shifting to the left by c units
f(x-c) shifting to the right by c units
f(x)+c shifting up by c units
f(x)-c shifting down by c units
g(x) = f(x - 2) - 2 =  |x - 2|  - 2
