Answer:
Option (3)
Step-by-step explanation:
Given function is,
f(x) = x⁴ + x³ - 2x²
= x²(x² + x - 2)
= x²(x² + 2x - x - 2)
= x²[x(x + 2) - 1(x + 2)]
= x²(x + 2)(x - 1)
So the factored form of the polynomial function is,
f(x) = x²(x + 2)(x - 1)
For x - intercepts,
F(x) = x²(x + 2)(x - 1) = 0
x = -2, 1
This function has even multiplicity = 2 at x = 0.
Therefore, graph of the function will touch the x-axis at x = 0
And at other roots x = -2, 1 has odd multiplicity = 1, so the graph will cross the x-axis.
Option (3) will be the correct option.
Answer:
-10
Step-by-step explanation:
y : x
= 5 : 4
4z = -8
= -8 / 4 = -2 = z
y : x
= 5 * -2 : 4 * -2
= -10 : -8
answer
45 minutes
explanation
using the equation C(m) = 0.1m + 1, C(m) is the cost of the phone call (5.50)
5.50 = 0.1m + 1 subtract 1 from both sides
4.5 = 0.1m divide both sides by 0.1
45 = m
m is the number of minutes, so 45 minutes
Answer:
b. 0
Step-by-step explanation:
The expression can be rewritten as:
As n becomes greater and begins diverging to infinity, each component of the sum converges to zero. Then, the limit of the sequence is zero.
1+1= 2
2+2= 4
3+3= 6
As you can tell from your answers it's is increasing by 2 each time.
HOPE THIS HELPS! ^_^
