hi, i need to graph a function with a domain of -4 is less than or equal to x which is less than or equal 4 and a range of -2 is less than or equal to y which is less than or equal to 6 and f(-3)=f(-1)=5

Can we clarify this a little? It seems that you are interested only in the range -4

The curve with the equation y=cosx/(2x+1), x> - 1/2 intersects the line y=1/2 at the point where x=α. i) Show that α lies between 0 and pi/2 ii)Use the iteration x(subscript n+1) - cosx(subscript n)-1/2 with x1=0 to find x3, giving your answer to 3d.p.

How do you draw the graph of x^2 + y^2 = 4

I really stuck, help pleeeaase asap.

How do you work out the 9th decile of a graph?

It's in a statistics practise paper, but i dont know what a decile is or how im supposed to work it out. Any help would be appreciated 🙂

Sketch a graph:

Hey guys 🙂 I'm kinda stuck on this question.. so i have to sketch the graph: y=(x2-4)/(x2+4x+6) so I know you have to find the vertical asymptote which doesn't exist by the way and the horizontal asymptote is y=0. the x-intercept=2, y-intercept=-2/3. Ok, now I need to draw the graph now but i don't really know how.

what must be the value of k if (k 6) lies on the graph of y=4x-6
