Q [628/630]

f(x) = 3x² + x – 15

f(2) = 3(2²) + 2 – 15

f(2) = 3(2 × 2) + 2 – 15

f(2) = 3(4) + 2 – 15

f(2) = 12 + 2 – 15

f(2) = 14 – 15

f(2) = -1

purple{boxed{blue{boxed{green{star{orange{ : : mathcal{JK} : : : {green{star}}}}}}}}}

Penjelasan dengan langkah-langkah:

f(x) = 3x² + x – 15

f(2) = 3(2)² + 2 – 15

f(2) = 3(4) + 2 – 15

f(2) = 12 + 2 – 15

f(2) = 14 – 15

f(2) = -1
