If f '(a) is defined, then f (x) is continuous at x = a. true or false

we are given

f'(a) id defined

we know that

f'(a) is derivative of f(x) at x=a

It means derivative of f(x) at x=a is defined

and we know that

All differentiable function is continuous

so, if f(x) is differentiable at x=a

then f(x) will also be continuous at x=a

so, this is TRUEAnswer

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
