The function is an increasing linear function
<h3>How to determine the function type?</h3>
The function is given as:
f(x) = 4.2x
The above function is a linear function, because linear functions are represented as:
f(x) = mx + b
Where m represents the slope.
A positive slope represents an increasing linear function.
By comparison;
m = 4.2
4.2 is positive
Hence, the function is an increasing linear function

Populations generally increase as an exponential function. In a short period of time, it could be approximated as linear (first degree). Depending what your teacher expects,
Linear model:
rate of increase = (y2-y1)/(x2-x1)=(103-98)/(2001-1994)=5/7 million per year.
From 2001 to 2018, there are 17 years. So add 17(5/7) millions to population of 2001.
exponential model:
Over 7 years, the ratio of populations is 103/98, so the annual ratio is (103/98)^(1/7)=1.007134, about 0.7134%.
Use the compound interest formula to find the population growing at the same rate from 2001 for 17 years:
population at 2018 = 103 millions * 1.007134^17 which is a little over 116 millions.
we just cross multiply but in order:
2 miles = 0.5 hours
y miles = 1 1/3 hours
(then cross multiply)
answer should be : 1.33 miles
Answer:
x = 9
Step-by-step explanation:
We are going to isolate x
14 - x = 5
subtract 14 from 5
-x = -9
multiply both sides by -1 to make x positive
x = 9
