Answer:

Step-by-step explanation:
Hypotenuse = x
Base = 4
Perpendicular = 
<u>Using Pythagoras Theorem:</u>

Ans: Option (1) <span>
Discontinuity at (1, 7), zero at ( negative four thirds , 0) </span>
Explanation:Given function:

Now if we plug in the x = 1, we would have discontinuity as function goes to infinity.
Now for f(1):
<span>If
Ellen deposited 6 773 dollars in her account and did not withdraw any amount
for 7 years.
Then she will earn this amount.
=> 1% interest rate per year
=> first year = 6 773 x .01 = 67.73
=> 6773 + 67.73 = 6840.73
=> Second year = 6840.76 * .01 = 68.4073
=> 68.4073 + 6840.76 = 6909.1673
=> Third year = 6909.1673 * .01 = 69.09
=> 6909.1673 + 69.09 = 6978.26
=>4th year = 6978.26 * .01 = 69.78
=> 6978.26 + 69.78 = 7004
=> 5th year = 7004 *.01 = 70.04
=> 7004 + 70.04 = 7074.04
=> 6th year = 7074.04 * .01 = 70.74
=> 70.74 + 7074.04 = 7144.78
=> 7th year = 7144.78 *.01 = 74.45
=> 7144.78 + 74.45 = 7216.23</span>
The answer will be 5(x^2-8)
