SOAL Q.
f(x) = 2.x² - x³ + 5
f(1) = 2.1² - 1³ + 5
f(1) = 2.(1.1) - (1.1.1) + 5
f(1) = 2.1 - (1.1) + 5
f(1) = 2 - 1 + 5
f(1) = 2 + 4
f(1) = 6
f(2) = 2.2² - 2³ + 5
f(2) = 2.(2.2) - (2.2.2) + 5
f(2) = 2.4 - (4.2) + 5
f(2) = 8 - 8 + 5
f(2) = 8 - 3
f(2) = 5
f(3) = 2.3² - 3³ + 5
f(3) = 2.(3.3) - (3.3.3) + 5
f(3) = 2.9 - (9.3) + 5
f(3) = 18 - 27 + 5
f(3) = 18 - 22
f(3) = -4
f(4) = 2.4² - 4³ + 5
f(4) = 2.(4.4) - (4.4.4) + 5
f(4) = 2.16 - (16.4) + 5
f(4) = 32 - 64 + 5
f(4) = 32 - 59
f(4) = -27
f(5) = 2.5² - 5³ + 5
f(5) = 2.(5.5) - (5.5.5) + 5
f(5) = 2.25 - (25.5) + 5
f(5) = 50 - 125 + 5
f(5) = 50 - 120
f(5) = -70
f(6) = 2.6² - 6³ + 5
f(6) = 2.(6.6) - (6.6.6) + 5
f(6) = 2.36 - (36.6) + 5
f(6) = 72 - 216 + 5
f(6) = 72 - 211
f(6) = -139
I Hope This Help!
