I got a different answer than what the book says...

so I need to find the formula of the graph.

[tex]H'(3)=f(3)=2[/tex]

[tex]m=\frac{\Delta y}{\Delta x}[/tex]

[tex]2=\frac{\Delta y}{x- \int^3_0 f(t)dt}[/tex]

[tex]y=2(x+2)[/tex]

[tex]y=2x+4[/tex]

the book's answer is 2x-8

where did I go wrong?
