Question

Consider the function f(x)=−2/3x+1.


What is f(3)?

f(3)=?

Answer 1

Alright well Graph the line using this slope and Y-intercept, or two points

Slope: - 2/3

Y - intercept: 1 Hope this helps have a nice day :)

Explanation:

And if you want i can explain the Answer with detail

Answer 2

f(3) =
`(7)/(9)`

Explanation:

The given function is

f(x)=
`(-2)/(3x)+1`

To find is the value of f(3)

Now we can find the value of a function by putting the vlaue in the given equation of the function

we can see that we have to find the value of f(3) and or given function is f(x)

so we have to put the value of x to be equal to 3 so that we can get the value of the desired function at a given point

Now

In this

x =3

f(x) =
`(-2)/(3x)+1` ................(i)

Put x = 3 in equation (i)

it becomes

f(3) =
`(-2)/(3*3)+1`

f(3) =
`(-2)/(9)+1`

Taking the LCM and solving it

LCM of 1 and 9 is 9 so it becomes

f(3) =
`(-2+9)/(9)`

f(3) =
`(7)/(9)`

which is the required value
