A carbon filter is used by a scientist to filter out small particles of soil and rocks from a water sample taken from a stream. The exponential function f(x) = 500(0.35) can
be used to model the function. Which of the following could be represented by the
value 500 in the function rule:

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
