Select the correct answer. Haley conducted a study which found that a cup of coffee contains 150 milligrams of caffeine. The amount of caffeine in the body each hour after consumption of one cup is 9% less than the previous hour. If Haley conducted her study for a total of 10 hours, which inequality represents the range of the exponential function that models this situation? 150 s f(x) s 355.1 58.41 s f(x) < 150 O s f(x) s 10 0 <f(x) s 150 Submit Reset

step-by-step explanation:

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
