Answer:
60,000 people
Step-by-step explanation:
Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,
x is the number of years after 2014
<u>We can find the number of people that bought the cell phone in 2020. </u><u>In year 2020, that will be after 6years</u>
Substitute x = 6 into the expression
y=-30x+240
y=-30(6)+240,=
y = -180 + 240
y = 60
Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

Answer: f(-1) = 4
<u>Step-by-step explanation:</u>
f(x) = 2x² - 3x - 1
f(-1) = 2(-1)² - 3(-1) - 1
= 2(1) + 3 - 1
= 2 + 2
= 4
