To Find:

f(-3x)

Step-by-step explanation:

$\sf Evaluate \ f(x) \ by \ substituting \ in \ the \\ \sf value \ of \ x = -3x \ into \ f(x): \\ \sf f( - 3x) = -2( - 3x) + 5 \\ \\ \ \ \ \ \ \ \ \ \ \ \ \ \sf = 6x + 5$

Answer:

a) f(x) = (-1/3)x + 8

b) f(x) = (1/3)x + 9

Step-by-step explanation:

f(x) = 1/3x - 8

a) To reflect across the x axis multiply f(x) by -1.

-f(x) = -1 (1/3x - 8)

= (-1/3)x + 8

b) to translate up 17 units add 17 to f(x)

f(x) + 17=

= 1/3x - 8 + 17

= 1/3x + 9

Answers are below.

Step-by-step explanation:

Problem 2:

Area = approx. 11.3 (rounded to nearest tenth)

A = 1 / 4b $\sqrt{4a^{2} - b^{2} = }$ 1/4 x 4 x $\sqrt{4 *6^2 - 4^2}=$ 11.31371

11.31371 rounded to the nearest tenth is 11.3
