Answer:

Step-by-step explanation:

To determine if (x - 2) is a factor of f(x)

Evaluate f(2) and if equal to zero then (x - 2) is a factor

f(2) = 2³ + 3(2)² - 2 - 18

= 8 + 12 - 2 - 18

= 0

(x - 2) is a factor of f(x) because f(2) = 0 → A

kati45 [8]

$f(x)=x^2-5;\ x\in\{-5;-3;\ 0;\ 1;\ 2\}\\\\f(-5)=(-5)^2-5=25-5=20\\f(-3)=(-3)^2-5=9-5=4\\f(0)=0^2-5=-5\\f(1)=1^2-5=1-5=-4\\f(2)=2^2-5=4-5=-1\\\\Answer:f(-5)=20$

I am taking a consumer math class to sharpen my financial skills in making educated decisions.

<h3>What is consumer math?</h3>

Consumer math is mathematics that uses basic math skills in real-life everyday situations.

Some real-life situations requiring consumer math abilities include shopping, calculating taxes, estimating the monthly budget, and calculating the interest rate for a loan.

Students taking consumer math classes can balance a checkbook, create a budget, buy a car or home, keep personal financial records, and pay taxes.

Thus, this consumer math course will enable me to make educated personal finance decisions.
