The number of roots of a quadratic function can be determined from its discriminant.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
The discriminant can be calculated as:
Disc = b² - 4ac
For the given equation:
Disc = 9 - 4(2)(1) =1
Since the value of discriminant is positive, the function will have two distinct roots.
So, the answer to this question is option B
In the given formula :
r = rate = 4.5% = 0.045
t = time = 7 years
P = principal = #3,700
e is an arbitrary number used in mathematics, which is approximately 2.7183
Replace the letters with the given information:
A = 3700e^0.045(7)
A = $5,069.96
The answer is C
