Answer:
The answer to your question is a = 2
Step-by-step explanation:
Data
root = -1
Polynomial p(x) = ax³ - x² + x + 4
Process
If -1 is a root of the polynomial, then, we must equal the polynomial to zero and substitute -1 and solve it for a.
1.- Equal to zero
ax³ - x² + x + 4 = 0
2.- Evaluate in -1
a(-1)³ - (-1)² + (-1) + 4 = 0
3.- Simplification
- a -1 - 1 + 4 = 0
-a + 2 = 0
4.-Solve for a
-a = -2
a = 2

Answer:
All below
Step-by-step explanation:
1. Before tax
500*0.7 (30% off means 100%-30% of the price = 70% or 0.7) = $350
2. Final selling price
350*1.13 (100%+13% as the price after adding 13% of tax to subtotal) = $395.5
Answer:
-9 ≤y≤8
Step-by-step explanation:
The range is the output values or the y values for this graph
The minimum y value is -9 and the maximum is 8
-9 ≤y≤8
