It is stated that their are closed circles on -4 and 3. This means, both -4 and 3 are also included in the interval.
The following regions are included in the range:
a) -4
b) Numbers between -4 and 3
c) 3
d) Numbers greater than 3
So, the number line represents:
x greater than or equal to -4 and x less than or greater to 3.
Therefore, the first option gives the correct combined inequality.
Answer:
−8x^4 + 5x^3 + x^2
Step-by-step explanation:
3x^3 + x^2 + 2 (x^3 − 4x^4)
Apply the distributive property.
3x^3 + x^2 + 2x^3 + 2 (−4x^4)
Multiply −4 by 2.
3x^3 + x^2 + 2x^3 − 8x^4
Simplify by adding terms.
Add 3x^3 and 2x^3.
5x^3 + x^2 − 8x^4
Simplify the expression.
Move x2.
5x^3 − 8x^4 + x^2
Reorder 5x^3 and −8x^4.
−8x^4 + 5x^3 + x^2
