Answer:
Step-by-step explanation:
A). An investment account earns 2.8% simple interest.
Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.
B). The price of a stock varies by 2.8% each week.
Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.
Therefore, the answer is NEITHER.
C). An investment account earns 2.8% compound interest, compounded monthly.
Formula to get the value of the final amount in the account is,
Final value = Initial value ×
Here 't' = Duration of investment
It's an EXPONENTIAL FUNCTION.
Answer:
Step-by-step explanation:
A solid straight line has a positive slope and goes through (0, negative 1) and (3, 0)
<em>Find the slope of the solid line</em>
The equation of the solid line in slope intercept form is equal to
we have
---> given problem
substitute
Everything above and to the left of the line is shaded
so the inequality is equal to
