Answer:
3 points: x = 1, x = 2 and x = 4
1 point: x = 6
Cross
Step-by-step explanation:
Points to remember:
- A zero of odd multiplicity will cross through the x-axis
- A zero of event multiplicity will only touch the axis i.e. be tangent to it.
The given zeros are:
- 1 with multiplicity of 1 (Odd Multiplicity)
- 2 with multiplicity of 3 (Odd Multiplicity)
- 4 with multiplicity of 1 (Odd Multiplicity)
- 6 with multiplicity of 2 (Even Multiplicity)
The graph will cross x-axis at zeros with odd multiplicity. Since zeros with odd multiplicity are 3, the graph will cross the x-axis at <u>3 points</u>: x = 1, x = 2 and x = 4
Similarly, the zero of even multiplicity is 1, so the graph will touch the x-axis at <u>1 point</u> only: x = 6
At the zero of 2, the graph of the function will <u>cross</u> the x-axis.
Use this formula:
K = K_0 * (1+r)^n
Insert and solve for n:
12600 = 6000 * (1+0.065)^n
n = 11.78
So about 12 quarters.
Hope that helped.

Lisa drove 61 miles
To divide fractions, firstly, you need to turn the 2nd fraction upside down. For example, 3/8 divided by 3/4 would be 3/8 divided by 4/3. After you have flipped the second fraction, you multiply them - 3*4 = 12. 8*3 = 24 so the answer would be 12/24. Which then could be cancelled down to 1/2. I hope this makes sense!!
