f(x) = x × x + x – x + x
f(22) = ….
Q.
f(x) = x × x + x – x + x
f(22) = 22 × 22 + 22 – 22 + 22
f(22) = 484 + 22 – 22 + 22
f(22) = 506 – 22 + 22
f(22) = 484 + 22
f(22) = 506
:)
Penjelasan dengan langkah-langkah:
f(x) = x × x + x – x + x
f(22) = 22 × 22 + 22 – 22 + 22
f(22) = (22×22) + 22 – 22 + 22
f(22) = 484 + 22 – 22 + 22
f(22) = 484 + (22 – 22) + 22
f(22) = 484 + 0 + 22
f(22) = 484 + 22
f(22) = 506
