Well, they are just plugging the x in and evaluating the exponent. Here's what the answers would be:

For the last one, it's no different then having an x there. t is just a variable as x is.

we have given that
f(x)=2^x. .

we need to find
f(t). .

we know that we need to plug t in place of x in the equation f(x)=2^x.

f(t)=2^t .for example for
f(4)=2^4

they have plugged 4 in place of x. so we plug in plug t in place of x .
