Solve system of equations graphically

Hello, I am a total beginer with matlab and need to solve a system of equations graphically

Here is the system of equations:

Thanks in advance!

Use "plot" to plot the two functions (e.g. for 0.5 <= x <= 2 and -2 <= x < = -0.5) and see where the curves intersect.

x=-5:5 

x = 1×11

-5 -4 -3 -2 -1 0 1 2 3 4 5

y=x.^3 

y = 1×11

-125 -64 -27 -8 -1 0 1 8 27 64 125

z=6./x

z = 1×11

-1.2000 -1.5000 -2.0000 -3.0000 -6.0000 Inf 6.0000 3.0000 2.0000 1.5000 1.2000

plot(x,y,x,z) 

am I doing this correctly?

I tested your code:

x  = -5:0.05:5;
y1 = x.^3;
y2 = 6./x;
plot(x, y1, x, y2)
xticks([-5:5])

Alternatively, you can also do like this:

Solve or plot this polynomial:

x = -2:0.01:2;
y = x.^4 - 6;
plot(x, y), grid on
yline(0, '--')
