The rate of change of a function occurring as a limit approaches zero is called

The rate of change of function occurring as limit approaches zero  is called as Derivative.

Step-by-step explanation:

Given:

The rate of change of function occurring as limit approaches zero

Solution:

Consider,  rate of change using limits is give by,

f'(a)=limit[ f(t)-f(a)/(t-a)]  as t tends to zero.

and it not possible to calculate t that last for zero seconds.

So this concept of Instantaneous rate of change and limit approaches zero is called as Derivative.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
