Let f(t) ANSWER: 1+ = t² - 1 t+3 Find f'(1)

Luda [366]

Answer:

f(1) = 3

Step-by-step explanation:

f(t) = t² - 1t + 3

we want to find f(1)

all we have to do is replace the t's with 1 and evaluate

f(1) = (1)² - 1(1) + 3

evaluate exponent 1² = 1

f(1) = 1 - 1(1) + 3

multiply

f(1) = 1 - 1 + 3

subtract

f(1) = 3

What is the square root of 141?

If you want it simplified (like with a calculator) it would be:
$\sqrt{141} =11.87$
