Can someone show me how to plot the following functions using axes that will produce a stright-line plot using Use the range 0 \< x \< 10
1) The power function y= 2x^-0.5 2) The exponential function y= 10^(1-x)
Thanks

In the first case you can use loglog():
x = 1:0.1:10;
y = 2*x.^(0.5);
loglog(x,y)
In the second case you can use semilogy();
x = 1:0.1:10;
y = 10.^(1-x);
semilogy(x,y)

I don't quite understand what you mean by using axes. But if you use
loglog(x,y)
for the first function and
semilogy(x,y)
for the second function, they'll look like straight lines, basically taking advantage of logarithms.
