Functional notation(pls show the solution) 3.) f(x)=5x²-2x+3. if x=3...

Step-by-step explanation:

the formula for compound interest is

where a is the amount after t years

p is the principal investment

r is the interest rate

n is the number of times it is compounded in a year

now plugging your given into this: p = 10,000, r = 2% or 0.02 in decimal form,

n = 4, since it is compounded quarterly, t = 5 years.

so maturity value = a = 10,000(1 + (0.02)/4)^(4x5) = php 11,048.96.

thus the interest = maturity value - principal = 11,048.96 - 10,000 = php 1,048.96.

hope this helps!
