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.
