MATLAB does not have implicit multiplication. Also, constant 'e' is not defined in MATLAB. You can create a function handle lie this

y = @(t) 1-2*exp(-2*t)+exp(-8*t)

Evaluate it like a function

y(1); % t = 1;

If you have the Symbolic toolbox, you can also write

syms t
y(t) = 1-2*exp(-2*t)+exp(-8*t);
