Plot the points for f(-1), f(0), and f(3) on the graph.
based on this function f(x)= 2x-3
if you can you can just give me the coordinates

Put the values of x to the equation of a function f(x).


f(x) = 2x - 3 → y = 2x - 3

f(-1) → x = -1 → y = 2(-1) - 3 = -2 -3 = -5 → (-1, -5)

f(0) → x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

f(3) → x = 3 → y = 2(3) - 3 = 6 - 3 = 3 → (3, 3)

Answer:

(-1,5) (0,-3) (3,3)

Explanation:

f(x)= 2x-3

let x = -1

f(-1) = 2(-1) -3

f(-1) = -2-3 = -5

(-1,-5)


f(0) = 2*0-3 = 0-3 = -3

(0,-3)


f(3) = 2*3 -3= 6-3 = 3

(3,3)
