Without setting a xlim how would i be able to plot the function y according to its domain (-∞, 1]. I get an error whilst plotting the graph and the plot function prints the invalid params D: (-∞,∞) hencewhy I want to use the fplot function.
x = [-1.5:0.01:1.5];
y= -sqrt((1-x))+nthroot(x.^2,5);
fplot(x, y);
Error:
Error using fplot (line 149)
Invalid parameter '-0.4050...'.

fplot() can be used for:
fplot() cannot be used for numeric vectors. You should use plot() for numeric vectors.

x = [-1.5:0.001:1.5];
y = -sqrt((1-x))+nthroot(x.^2,5);
mask = imag(y) ~= 0 | real(y) > 1;
y(mask) = nan;
plot(x, y);
