F(x) = x2. What is g(x)? g(x)

Answer:

f(x) = x2    g(x) = 5x

Step-by-step explanation:

f(x) = x2    g(x) = 5x

There are two composite functions we could get from this:

f(g(x)) or  (fog)(x)

g(f(x)) or (gof)(x)

f(g(x)) = f(5x) = (5x)2 = 25x2   Domain = all real numbers

g(f(x)) = g(x2) = 5x2    Domain = all real numbers

Note that the composite of two functions is NOT the same

as multiplying the two functions together.

f(x)*g(x) = x2(5x) = 5x3

Help me with this question, please
anzhelika [568]

Answer:

Part 1: [ -4 = -8 ]

Part 2: Inconsistent

Step-by-step explanation:

<u>Part 1</u>

1. Move all terms that don't contain x to the right side:

3x - 6y+6y = -12+6y

= 3x = -12 + 6y

2. Isolate x:

\frac{3x}{3} = \frac{-12+6y}{3}

x = -4 + 2y

3. Substitute the new expression into the original:

-4 + 2y - 2y = -8

4. Simplify:

-4 + 0 = -8

[ -4 = -8 ]

<u>Part 2</u>

The two solutions are not equal in value, so, we can conclude that the system of equations has no solution, or is inconsistent.

hope this helps!
