Question

Dik: notasi fungsi fx -> 2x*kuadrat 2* - × + 1 dengan domain {-2,-1,0,1,2}

Tentukan :
a. Rumus Fungsi
b. Range
d. Himpunan pasangan berurutan
Bantuin yaahhhh ,,, :);)

Answer 1

Answer 2

A. Rumus fungsi = f(x) = 2x² -x +1
b. f(-2) = 2(-2)² -(-2) +1
           = 8 +2 +1
           = 11
   f(-1) = 2(-1)² -(-1) +1
           = 2 +1 +1
           = 4
  f(0) = 2(0)² -0 +1
         = 1
  f(1) = 2(1)² -1 +1
       = 2 -1 +1
       = 2
  f(2) = 2(2)² -2 +1
         = 8 -2 +1
         = 7
Range = {1, 2, 4, 7,11}
c. {(-2,11),(-1,4),(0,1),(1,2),(2,7)}
