Answer:

$f°g(x) = 14x +2$

Step-by-step explanation:

$f°g(x) = f(g(x)) \\f°g(x) = 7g(x) +9 \\ f°g(x) = 7(2x -1) +9 \\ f°g(x) = 14x -7 +9 \\ f°g(x) = 14x +2$

For the function f defined by f(x)=5x−12 find f(−x),−f(x), and −f(−x).

Slav-nsk [51]

$f(x) = 5x-12$

$f(-x) = 5(-x)-12 = -5x-12$

$-f(x) = -(5x-12) = -5x+12$

$-f(-x) = -(5(-x)-12) = -(-5x-12) = 5x+12$

This is probably asking you to consider the symmetry of f(x). If f(x) is equal to f(-x), then f is symmetric about the origin. If f(x) is equal to -f(x), then f is symmetric about the y-axis.

Solve 5 over x plus 8 equals 3 over x for x and determine if the solution is extraneous or not.

$\frac{5}{x+8}=\frac{3}{x}\ \ \ Domain\ D:x+8\neq0\to x\neq-8\ and\ x\neq0\\\\cross\ multiply\\\\5(x)=3(x+8)\ \ \ |use\ distributive\ property\ a(b+c)=ab+ac\\\\5x=3(x)+3(8)\\\\5x=3x+24\ \ \ \ |subtract\ 3x\ from\ both\ sides\\\\2x=24\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\huge\boxed{x=12\in D}$
