Answer:
x^3 +3x^2 +6x
Step-by-step explanation:
Eliminate parentheses using the distributive property. Collect terms. Standard form has the exponents decreasing.
= 8x -6x^3 +5x^2 -2x^2 -2x +7x^3
= x^3(-6 +7) +x^2(5 -2) +x(8 -2)
= x^3 +3x^2 +6x

Answer:
Option D y=3
Step-by-step explanation:
The question in English is
Which of the following functions is a constant function?
we know that
A <u>constant function</u> is a function whose output value is the same for every input value
so
<u><em>Verify each case</em></u>
case A) y=x+1
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case B) y=x+2
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case C) x=y+3
This is not a constant function, this is a linear equation
Is a function whose output value is different for every input value
case D) y=3
This is a constant function
Is a function whose output value is the same for every input value
