Question

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?

f(–3) = –5

f(–3, –5) = –8

f(–5) = –3

f(–5, –3) = –2

Answer 1

f(-3)=-5

Explanation:

Answer 2

`f(-3)=-5`

Explanation:

we are given a point as

(-3,-5)

we know that any point can be represented as (x,y)

so, (x,y)=(-3,-5)

now, we can find x and y

we get

`x=-3`

`y=-5`

we know that any function can be represented as

`y=f(x)`

It means when x=-3 , y=-5

so, we can plug these values

and we get

`-5=f(-3)`

`f(-3)=-5`
