Answer: y = {5, 4, 8}
<u>Step-by-step explanation:</u>
f(x) = 4 + x²
f(-1) = 4 + (-1)²
= 4 + 1
= 5
f(0) = 4 + (0)²
= 4 + 0
= 4
f(1) = 4 + (1)²
= 4 + 1
= 5
f(2) = 4 + (2)²
= 4 + 4
= 8

Step-by-step explanation:
Total number of books, n = 18
Number of books to be selected, r = 7
Since, the order of arrangement doesn't matter ;
We use the combination formula :
nCr = n! ÷ (n-r)! r!
18C7 = 18! ÷ 11!7!
18C7 = (18*17*16*15*14*13*12) ÷ (7*6*5*4*3*2*1)
18C7 = 160392960 / 5040
18C7 = 31,827 ways
