f(x) = 45 × 7x + 4x² - 7x
f(9) = 45 × 7(9) + 4(9²) - 7(9)
f(9) = 45 × 63 + 4(9.9) - 63
f(9) = ( 45×63 ) + 4(81) - 63
f(9) = 2.835 + 324 - 63
f(9) = 3.159 - 63
f(9) = 3.096

Penyelesaian ✍️
f(x) = 45 × 7x + 4x² - 7x
f(9) = 45 × 7(9) + 4(9²) - 7(9)
f(9) = 45 × 63 + 4(9.9) - 63
f(9) = ( 45×63 ) + 4(81) - 63
f(9) = 2.835 + 324 - 63
f(9) = 3.159 - 63
f(9) = 3.096
