Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs.

-BARSIC- [3]

Answer:

See below

Step-by-step explanation:

The x-intercepts are the points with y- coordinate of 0

(x - 3)(x + 8) = 0
x - 3 = 0 or x + 8 = 0
x = 3 or x = - 8

a) x-intercepts are

3 and - 8

b) midpoint of x-intercepts is

(3 - 8)/2 = - 5/2 = - 2.5

c) The extheme value has x- coordinate of - 2.5 and y- coordinate

(-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25

d) f(- 2.5) = - 30.25

∵ The formula of the compound interest is

$A=P(1+\frac{r}{n})^{nt}$

→ A is the new amount

→ P in the initial amount

→ r is the interest rate in decimal

→ n is the number of periods

→ t is the time

∵ The initial amount is 800 dollars

∵ The annual rate is 3% = 3/100 = 0.03

∵ It is a compounded annually

∴ n = 1

∵ t = 5 years

→ Substitute all of these values in the formula above

$\begin{gathered} A=800(1+\frac{0.03}{1})^{1(5)} \\ A=800(1+0.03)^5 \end{gathered}$

→ Use the calculator to find the answer

∴ A = 927.4192594 dollars
