c)

We know that:

$(f\circ g)(x)=2x+4$

to find the function at x=1 we just plug this value of x in the expression found:

$(f\circ g)(1)=2(1)+4=2+4=6$

Therefore:

$(f\circ g)(1)=6$

d)

We know that:

$(g\circ f)(x)=2x+7$

Then we have:

$(g\circ f)(1)=2(1)+7=2+7=9$

Therefore:

$(g\circ f)(1)=9$
