Step-by-step explanation:
<u>Given:</u>
- Investment P = $20000
- Time t = 7 years
- Interest rate r = 5.5% = 0.055
a. <u>compounded semiannually, n = 2</u>
b. <u>compounded quarterly, n = 4</u>
c. <u>compounded monthly, n = 12</u>
d. <u>compounded continuously</u>
Since the limit becomes the undetermined form
it means that both polynomials have a root at . So, we can fact both numerator and denominator:
So, the fraction becomes
Now, as x approaches 1, you have no problems anymore:
A) the posible roots of the function f(x)=x⁴-3x³-5x²+21x+22 are:
=-1,+1,-2,+2,-11,+11,-22+22.
b)
one zero of the funtion can be: x=-1 ⇒y=0 (-1,0)
c)
other zero of the funtion is: x=-2 ⇒y=0 (-2,0)
d)
if x=0 then y=22 (0,22)
e) In the file is the graph.
=-1,+1,-2,+2,-11,+11,-22+22.
b)
