​f (x) = 9x² - 3x³ ; x = 2

f (2) = 9 (2)² - 3(2)³

f (2) = 9 (4) - 3 (8)

f (2) = 36 - 24

f (2) = 12

f (x) = 12x⁴ + 8x⁵ ; x= 3

f (3) = 12 (3x)⁴ + 8 (3) ⁵

f (3) = 12 (16) + 8 (243)

f (3) = 192 +,1944

f (3) = 2,187​

​f (x) = 10x⁶ + 17x³ ; x = 7

f (7) = 10 (7)⁶ + 17 (7)³

f (7) = 10 (117,649) + 17 (343)

f (7) = 1,176,490 + 5,831

f (7) = 1,182,321

​f (x) = 7x⁵ + 8x⁶ ; x = 2

f (2) = 7 (2)⁵ + 8 (2)⁶

f (2) = 7 (32) + 8 (64)

f (2) = 224 + 512

f (2) = 736

f (x) = 20x⁴ + 27x⁵ ; x = 9

f (9) = 20 (9)⁴ + 27(9)⁵

f (9) = 20 ( 6,561) + 27 (59,049)

f (9) = 131,220 + 1, 594, 321

f (9) = 1, 725, 541​
