Step-by-step explanation:

1. X/2 when x = 1/2

Putting value of x in the equation

1/2 /2 = 0.25

2. 2x2 - 8 when x = 3

2(3)2 - 8

= 2(9) - 8

= 18 - 8 = 10

3. 4(x - 7)3 + 5 when x = 9

4 (x3 - 21x2 + 147x - 343) + 5

Putting value of x

4((9)3 - 21(9)2 + 147(9) - 343) + 5

4(729 - 1701 + 1323 - 343) + 5

4(8) + 5

= 32 + 5 = 37
