Question

Two different plants grow each year at different rates, which are represented by the functions f(x) = 4x and g(x) = 5x + 2. What is the first year the f(x) height is greater than the g(x) height? A. Year 0 B.Year 1 C.Year 2 D.Year 3

Answer 1

f(x)>g(x)
4x>5x+2
because x represents the number of years, it has to be a positive number, 4x will never be larger than 5x.
the answer is never.

Answer 2

The correct answer is YEAR 2. I did the test and that was the correct answer
