The answers to the questions
Graph F(x) = |x - 1|
1 answer:
- Modulus function is a function gives absolute value of a number or variable.
- It gives magnitude of the number or variables.
- It is also known as an absolute value the function.
- The result of this modulus function is always positive.
Draw the graph:
f(x) = |x-1|
f(x) = -(x-1) when x-1 is negative
f(x) = (x-1) when x-1 is positive
when x = -2, f(x) = 3
when x = -1, f(x) = 2
when x = 0, f(x) = 1
when x = 1, f(x) = 0
when x = 2, f(x) = 1
Using this values, draw the graph of f(x) = |x-1|
Hence, the required modulus of x-1 graph.

I'll use my own formula (similar to yours tho)
A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years
so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so
divide both sides by P
simplify
take the ln of both sides
divide both sides by 4ln(1.03)
use calculator
5.86244=t
