Equivalent expressions are similar expressions that may have different forms but when a value is replaced with the variables in the same form provides the same answer.

From the information given, If:

r(x) = 3x - 1
s(x) = 2x + 1

Then the fractional form can be an expression as:

$\mathbf{(\dfrac{r}{s})(x)= \dfrac{3x-1}{2x+1}}$

where;

x = 6

$\mathbf{(\dfrac{r}{s})(6)= \dfrac{3(6)-1}{2(6)+1}}$

$\mathbf{(\dfrac{r}{s})(6)= \dfrac{18-1}{12+1}}$

$\mathbf{(\dfrac{r}{s})(6)= \dfrac{17}{13}}$

. Let f and ???? be the functions given by f(x) = x2 and ????(x) = x|x|.

In-s [12.5K]

Answer:

Step-by-step explanation:

let ????=g

g(x)=x|x|

if x<0,then |x|=-x

-67<0

|-67|=-(-67)=67

g(-67)=-67(67)=-67²

f(-67)=(-67)²=67²

f(-67)+g(-67)=67²-67²=0
