I have been given an exercise to plot this equation h = h[1] = 1, h[2] = 3, h[3] = -2, h[4] = 9, h[5] = 7; I am very new to Matlab and I am confused as to whether I have to define some of the variables or simply just insert the equation? Sorry I cannot provide much more information I am a Matlab novice.

Maybe you want to do something like:
h = [1, 3, -2, 9, 7];
ft_h = fft( h );
ft_h = sqrt( ft_h .* conj( ft_h ) );
plot( ft_h );

try :
n=500;
[g,w]=freqz(h,n);
figure,plot(w,(abs(g)))
