Question

What is the approximate value fo the function at x=6?

Answer 1

first draw a vertical line that passes through x = 6 on the x axis (shown in blue in the attached image)

Answer 2

ok yhen what?

Answer 3

mark the point of intersection between the red curve and the blue line (green point)

then extend a horizontal line from that point of intersection until you hit the y axis

see attached

Answer 4

so where does that green horizontal line end up on the y axis?

give a rough approximation (it doesn't have to be perfect)

Answer 5

like 6, and 2.5? im not quite sure if i get it

Answer 6

only look at the y axis and where the green line touches the y axis

Answer 7

to me, it looks just a bit below 2.5, so maybe 2.3 or 2.2

Answer 8

like 2.3? or 2.2 that makes sense lol

Answer 9

so if x = 6, then y is roughly 2.3 or 2.2

the ordered pair of that green point is (6, 2.3) or (6,2.2) however you interpret it

Answer 10

the y value of the point on the red curve is the output of the function

x is the input of the function

Answer 11

Thank you! what about this one? its similar but im still not quite understanding it

Answer 12

what are the instructions?

Answer 13

What is the approximate value of the function at x = -8?

Answer 14

draw a vertical line through x = -8 on the x axis

mark where the vertical line crosses the red function curve

then draw a horizontal line until you reach the y axis

Answer 15

tell me what you get

Answer 16

is it gonna be 2? -2?

Answer 17

not sure how you're getting -2

Answer 18

it's really close to +2, maybe like 1.9 or something

Answer 19

ugh this stuff is so confusing. so its rounded to 2? positive?

Answer 20

lohhh thats what i meant was 2 i was just loking at it and thought -2

Answer 21

yeah if you have to go to the nearest whole number then 2 works

Answer 22

Thank you so much!!
