What's In
Activity: Working Backwards
Consider the function f(x) = 4x + 3. When evaluating the function at x
equals to 2, it gives a y value of 11. If working from 11, what must be the
complete process to get back 2 at the start?​


Sagot :

Answer:

let f(x) = y,

since y = 11, Then

[tex]11 = 4x + 3[/tex]

[tex]11 - 3 = 4x[/tex]

[tex]8 = 4x[/tex]

[tex]2 = x[/tex]

or

[tex]x = 2[/tex]
