For the funcations f(x) =2x-6 and g(x) =5x+1 which composition produces the greatest output
soldi70 [24.7K]

Answer:

C. f(g(x)) produces the greater output.  

Step-by-step explanation:

ƒ(x) = 2x - 6

g(x) = 5x + 1

f(g(x)} = 2(5x + 1) - 6 = 10x + 2 - 6 =10x - 4

g(f(x)) = 5(2x- 6) + 1 = 10x - 30 + 1 = 10x - 29

f(g(x)) - g(f(x)) = 10x - 4 - (10x -29) = 10x - 4 - 10x + 29 = 25

f(g(x)) is always 25 units greater than g(f(x)), no matter the value of x.

Thus f(g(x)) produces the greater output.

Find the value of f(-6).yy = f(x)108642-10-8-6-422468.10-2-4-6-8
Gennadij [26K]

The given graph is a downward parabola.

The roots of the equation is -2 and -8, and the vertex is (-5,7).

The general root form of parabola will be,

a(x-(-2))(x-(-8))=a(x+2)(x+8).

The value of a can be determined from the coordinate of vertex,

\begin{gathered} y=a(x+2)(x+8) \\ 7=a(-5+2)(-5+8) \\ 7=a\times(-3)(3) \\ a=\frac{-7}{9} \end{gathered}

Thus, the required quadratic is,

f(x)=\frac{-7}{9}(x+2)(x+8)

The value of f(-6) can be determined as,

\begin{gathered} f(-6)=\frac{-7}{9}(-6+2)(-6+8) \\ =6.22 \end{gathered}

Thus, the requried value of f(-6) is 6.22.
