    f(3) = 42

    Step-by-step explanation:

    f(x) = 5 {x}^{2}  - 2x + 3

    f(3) = 5(3)^{2} -2(3) + 3

    f(3) = 5(9) - 2(3) + 3

    f(3) = 45 - 6 + 3

    f(3) = 39 + 3

    f(3) = 42

    the formula for compound interest is

     a = p (1 + \frac{r}{n})^{nt}

    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!
