Answer 1

Penjelasan dengan langkah-langkah:

f(x) = 1x + 2x ÷ 3x × 4x - 5x

f(x) = 1x + (2/3)x × 4x - 5x

f(x) = 1x + (8/3)x^2 - 5x

f(x) = x + (8/3)x^2 - 5x

Part-A

f(1) = 1 + (8/3)(1)^2 - 5(1)

f(1) = 1 + 8/3 - 5

f(1) = 11/3 - 5

f(1) = 11/3 - 15/3

f(1) = -4/3

Part-B

f(2) = 2 + (8/3)(2)^2 - 5(2)

f(2) = 2 + (8/3)(4) - 10

f(2) = 2 + 32/3 - 10

f(2) = 38/3 - 10

f(2) = 38/3 - 30/3

f(2) = 8/3 = 2 2/3

Part-C

f(3) = 3 + (8/3)(3)^2 - 5(3)

f(3) = 3 + (8/3)(9) - 15

f(3) = 3 + 24 - 15

f(3) = 27 - 15

f(3) = 12
