The graph of f(x) = x2 – 3x2 + 4 is shown
IRISSAK [1]

Answer:

2 is the answer that I would give. The question says <u>distinct</u> solutions does this graph have.

Step-by-step explanation:

You are asked only how many times this crosses the x axis. You are not asked for an exact value. So the thing to do is graph the polynomial.

y = x^3 - 3x^2 + 4

The graph says that x = -1 with a multiplicity of 1

It also says that x=2 is a solution with a multiplicity of 2 (meaning there are 2 roots are the same).

So this polynomial factors into y = (x + 1)(x - 2)(x - 2)

WHO'S UP AND WANTS TO HELP??
lesya692 [45]
I believe this question is referring to purchasing a discount on a loan's interest rate by putting more towards closing costs. For mortgages, sometimes they will allow you to "buy" a smaller interest rate. For example: 
<span>Loan A has an interest rate of 4.5% and no closing costs. </span>
<span>Loan B has an interest rate of 4.375%, but has $1000 in closing costs. </span>

<span>Normally, Loan A would be the better choice if you plan on keeping the home short term, but Loan B would be more beneficial for keeping the loan long-term. I don't really care to spend the time that is necessary to come up with an actual scenario, but I hope that helps enough for you to understand the question.</span>

The answer is 2x^2+2x-14. Using the distributive property, you can find that the area of the pool is x^2+3x+2. Next, you have to find the area of the deck. This will be 3x^2+5x-12. Finally, you subtract the area of the deck by the area of the pool. (3x^2+5x-12)-(x^2+3x+2) comes out to be 2x^2+2x-14. Hope this helps!!
