The values for which the graph is negative and increasing are all real values of x where 1 < x < 4.
Given
The graph of function;
[tex]\rm f(x) = (x + 2)(x - 4)[/tex]
What is a graph?
A graph goes from being negative to positive (or the other way around) by passing through the x-axis. in other words when f(x) = 0.
Then,
[tex]\rm f(x) = (x + 2)(x - 4)=0\\\\x+2 =0\ x=-2\\\\x-4=0\ x=4[/tex]
For increasing and decreasing for anything other than a quadratic and linear function you need calculus.
The function is negative below the zeros which would be from -2 to 4.
It would be increasing from the vertex to zero,4.
Hence, the values for which the graph is negative and increasing are all real values of x where 1 < x < 4.
