Step-by-step explanation:
f(x) = -2x^2 - 4 for x = 3
f(3) = -2(3)^2 - 4
f(3) = -2(9) - 4
f(3) = -18 - 4
f(3) = -22

Answer:
110 pages
Step-by-step explanation:
Let number of pages read on 1st day = x
-> No. of pages read on 2nd day = 2x
& No. of pages read on 3rd day = x - 6
Total no of pages read = 458
-> x + 2x + x - 6 = 458
-> 4x - 6 = 458
-> 4x = 458 + 6
-> 4x = 464
-> x = 464/4
-> x = 116
No of pages read on third day = x - 6 = 116 - 6 = 110
