(3x^2-2x+4)+(5x^2+6x-8) - Combine like terms
8x^2+4x-4
(f+g)(x)=8x^2+4x-4
Use the trigonometric function.
You are multiplying the 3x by 6 which means c is correct

Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation
is similar to equation of line
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
