what does f x greater than 0 mean We want the values of x that give a y value greater than 0 Let s say that f x x 2 10 The graph below shows y f x graph x 2 10 6 6 15 15 When we want f x 0 we want y 0 or all the values of x where f x 0
A If f x 0 on an interval then f is increasing on that interval b If f x 0 on an interval then f is concave upward on When we see the notation f x 0 it means that the value of the function f x is greater than zero This statement tells us that the graph of the function f x lies entirely above the x axis To

Solution set of f x 0 x intercept s of graph Solution set of f x 0 x values corresponding to part of graph ABOVE x axis Free unlimited online practice F g x f x 1 so just substitute x 1 in for all x values in f x In the end you should get x 3 5x 2 2x 8 For the second part x 3 5x 2 2x 8 0 you factor it out Each of those parts has
Let f x x 4 2x 3 3x 2 2x 1 Prove that f x ge 0 My thought is I need factor the function into sum or difference of perfect squares to show it s always non negative If f x is a maximum then for h 0 this is geq 0 so the limit when h nearrow 0 is while for h 0 this is leq 0 so the limit when h searrow 0 is Hence the limit is 0 similarly if f x is a minimum

It means a function f that takes a parameter x such that f does something to x and returns a result such that x s actual value doesn t matter For example if f x x 2 then what x actually If the domain of f is the set F and the domain of the function g is G then a typical interpretation of f g is text For all x in F cap G we have f x g x It is not
