Given that f(x) = x²-1,
a) Find f(5)
b) Find f-'(x)
c) Find f-'(8)
Answers
Answer:
step by step as shown
Step-by-step explanation:
f(x) = x²-1
f(5) = 5² - 1 = 24
f⁻¹(x)
y = x²-1
x = y² - 1 swap x and y
y² = x+1 ... x+1 ≥ 0 x≥-1
y = √x+1
f⁻¹(x) = √x+1
f⁻¹(8) =√8+1 = √9 = 3

Jared is rounding some numbers to the nearest tenth. Select the number that will have a 3 in the tenths place after rounding. (2 points)
3.03
4.28
5.39
6.43
Answers
Answer: B) 4.28
The 2 is in the tenths place, and 8 is to the right of it. The 8 is five or larger, so that means we bump the 2 up to 3. We erase the 8. So we go from 4.28 to 4.3; we have a 3 in the tenths place as instructed.
We can think of 4.3 as 4.30
Note how 4.28 is closer to 4.30, than it is to 4.20
