If ( f ∘ g)(x) = x2 - 6x + 8 and g(x) = x - 3, what is f(x)?
DochEvi [55]
\bf \begin{cases}&#10;(f\circ g)(x)=x^2-6x+8\\\\&#10;(f\circ g)(x)=f(~~g(x)~~)\\\\&#10;g(x)=x-3\\&#10;\end{cases}&#10;\\\\\\&#10;\textit{now, one probability is }x^2-1&#10;\\\\\\&#10;f(x)=x^2-1\implies f(~~g(x)~~)=(x-3)^2-1&#10;\\\\\\&#10;f(~~g(x)~~)=(x^2-6x+9)-1\implies f(~~g(x)~~)=x^2-6x+8

Given:

The figure of two quadrilaterals.

In ABCD,AB=18,BC=20,CD=22,AD=24

In EFGH,EF=27,FG=30,GH=34, EH=36

To find:

Whether the figures are congruent, similar or neither.

Solution:

Ratio of corresponding sides are:

\dfrac{AB}{EF}=\dfrac{18}{27}

\dfrac{AB}{EF}=\dfrac{2}{3}

Similarly,

\dfrac{BC}{FG}=\dfrac{20}{30}

\dfrac{BC}{FG}=\dfrac{2}{3}

\dfrac{CD}{GH}=\dfrac{22}{34}

\dfrac{CD}{GH}=\dfrac{11}{17}

And,

\dfrac{AD}{EH}=\dfrac{24}{36}

\dfrac{AD}{EH}=\dfrac{2}{3}

Clearly, \dfrac{AB}{EF}=\dfrac{BC}{FG}=\dfrac{AD}{EH}\neq \dfrac{CD}{GH}.

All corresponding sides are not proportional.

Therefore, the figures are neither similar nor congruent. Hence, third option is correct.
