I need to find the derivative of this function y = ?(2+5x) and evaluate it at x = 1 Hoping there is a simple way to accomplish this.

see http://reference.wolfram.com/language/ref/D.html

Mathematica:

y = ?(2+5x);
Y = D[y,x];
x =1;
Y

Wolframalpha:

D(sqrt(2+5x),x)

D(sqrt(2+5x),x) at x=1

worked for me.
