Answer:
Option B
Step-by-step explanation:
we have
we know that
<u>The vertical line test </u>is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x
In this problem
The given function passes the vertical line test
therefore
f(x) is a function
<u>The Horizontal Line Test</u> is a test use to determine if a function is one-to-one
If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.
In this problem
The given function fails the horizontal line test
because for f(x)=0 x=-3, x=-1, x=3
therefore
It is no a one-to-one function
Answer:
The answer to your question is: t = 4 hours
Step-by-step explanation:
Data
Milton v = 8 km/h
time = 4 hours
Harriet v = 16 km/h
Formula
v = d/t or d = vt
Process
Find the distance travel by Milton in 4 hours
d = (8 )(4) = 32 km
Find the distance travel by each person
Milton d = 32 + 8t
Harriet d = 16t
Match them 16t = 32 + 8t
Solve for t 16t - 8t = 32
8t = 32
t = 32/8
t = 4 hours
The answers are
a) the domain is all real numbers
d) the input to an exponential function is the exponent
e) the base represents the multiplicative rate of change
hope this helps :)
Z = 70 because 5x5 is 25 so u have to do 14x5 which is 70
