Answer question one and show work.

likoan [24]

Answer:

x = 28

Step-by-step explanation:

angle 1 and angle 2 are complementary (their sum is 90°)

x + 5 + 2x + 1 = 90 add like terms

3x + 6 = 90 subtract 6 from both sides

3x = 84 divide both sides by 3

x = 28

The function f(x)=3 (x+6)^2+8 is shifted 4 units up and 3 units right to form another function g(x). What is g(x)?

iVinArrow [24]

Answer:

$g(x) = 3\cdot (x+3)^{2}+12$

Step-by-step explanation:

There are two operations involved:

Vertical translation:

$f'(x) = f(x) \pm c,\,c\in \mathbb{R}$ (1)

Note: Positive sign represent a translation upwards.

Horizontal translation:

$f'(x) = f(x\pm c), x\in \mathbb{R}$ (2)

Note: Positive sign represent a translation leftwards.

Then, the new function must be:

$g(x) = f(x-3)+4$

$g(x) = 3\cdot (x+3)^{2}+12$
