How do you write an equation to represent a real world situation

5.(04.07) two different plants grow each year at different rates, which are represented by the functions f(x) = 4* and g(x) = 5x + 2. what is the first year the f(x) height is greater than the g(x) height? year 3 year 0 year 2 year 1

With: label the vertices and all the elements needed. find x

Which of the following is true for the relation f(x)=2x^2+1
