Find each function, find f(a+h) and f(a+h)-f(a)

a) f(x)=5x-2

• Calculus -

5(a+h) -2 = 5a + 5h - 2
5(a) -2 = 5 a - 2
--------------------------subtract

now if we were doing calculus we would divide that by h and then let h go to 0
5 h/h = 5
and we call that the "derivative" of f(x)=5x-2

• Calculus -

May I know where you got 5a + 5h - 2

• Calculus -

f(a+h) = 5(a+h) - 2

5(a+h) -2 = 5 a + 5 h - 2

Thank you~
