Step-by-step explanation:
Answer:
16.03
Step-by-step explanation:
5 is a whole number so keep it as 5 then 4 is in the tenths place so that means have ten for the denominator so 5 and 4/10 is the mixed number then simplified to 5 and 2/5
Answer: 1st one is A and 2nd one is also A
Step-by-step explanation:
Domain is X
Range is Y
(It is alphabetical order: D, R)
Given: f(x) = x³ - 4x² + 2
Note that
f(x+h) - f(x) = (x+h)³ - 4(x+h)² + 2 - (x³ - 4x² + 2)
= x³ + 3x²h + 3xh² + h³ - 4(x² + 2xh + h²) + 2 - x³ + 4x² - 2
= 3x²h + 3xh² + h³ - 8xh - 4h²
Therefore
[f(x+h) - f(x)]/h = 3x² +3xh + h² - 8x - 4h
That is
f'(x) = 3x² - 8x
f'(3) = 3(3²) - 8(3) = 3
Answer: 3
