Please help! I don’t understand this!

f(3) = 13

Step-by-step explanation:

Given f(x) =  2 -3x + 4

For f(3), solve by using the polynomial remainder theorem, need to dive by (x-3) because the remainder theorem says if a polynomial f(x) is divided by x-r, the remainder is a constant f(r);

therefore f(3) = 13 (see image attached)

step-by-step explanation: noo

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
