At the end of each year, the amount is (1 + 11%) = 1.11 times the amount at the beginning of the year. When that multiplier is applied 5 times, the result is
$30 * 1.11^5 ≈ $50.55

Determine the function f(x) satisfying the given conditions.

Furkat [3]

<span>f''(x) means function is of grade 1
f(x) = ax + b

f'(x) = a
f'(5) = 1 </span>⇒ a = 1

f(4) = -2
f(4) = 1×4 + b
-2 = 4 + b
b = -6

f(x) = x - 6

Consider this expression

Sloan [31]

Answer:

$\displaystyle \large{(x + 9)(x - 8)}$

The value of a is 9 and b is -8

Step-by-step explanation:

$\displaystyle \large{(x + a)(x + b) = {x}^{2} + (a + b)x + ab}$

We need to find two numbers that add up or subtract off to 1.

Then we also use the same two numbers that multiply and get -72.

Let's see:-

9 and -8 seem like correct values.

Because 9+(-8) is 9-8 = 1

And 9(-8) is -72.

Therefore:

$\displaystyle \large{ {x}^{2} + x - 72 = (x + 9)(x - 8)}$

The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)
