"Find the equation for equlibrium catch/harvest, and illustrate this equation in a koordinate system with the given values"

Equation i came up with is this,

h(E)=F(x) = q*K*E - ( (q^2 * K * E^2) / r )

-E is effort F(X) the catch

Values given are

q= 0.004

K =1.5 mil tonns

r= 0.6

Issue is illustrating it, I just get a straight line.

You have two = signs!!

What do you want to plot against what (h vs E?)?

Think i worked it out. I used , instead of .

Anyone want to help still? I am really s**t at illustrating stuff like this.

Need a prog/site that makes it easy to copy/paste it into a word doc.

And ye catch h (y-axis) vs effort E (x-axis)

You could try the online Desmos graphing calculator.
