Question: Let f ( x ) = e x . Show that a . f ( x + h ) - f ( x ) h

Let f(x)=ex. Show that
a.f(x+h)-f(x)h=ex(eh-1h).
b.f(x+y)=f(x)f(y).
c.f(-x)=1f(x).
a. Show that f(x+h)-f(x)h=ex(eh-1h). Let f(x)=ex.
First find f(x+h).
f(x+h)=ex+h
Substitute the previous answer into the numerator.
-exh(Do not simplify.)
Let f ( x ) = e x . Show that a . f ( x + h ) - f
