Answer:
x - 8
Step-by-step explanation:
Plug in -1 for x and you get x - 8
A.) Yes you can, the expression would be (2.95 x Y) + 4 = X
B.) (2.95 x 24) + 4 = $74.80
C.) (2.95 x 57) + 4 = X
2.95 x 57 = 168.15 + 4 = 172.15
so basically they can buy 57 books without going over $175
Looking at the function h(t), it is a polynomial function.
The domain of this type of function usually is all real numbers.
But in this case, since the independent variable t represents the time, its value can't be negative, it usually starts at t = 0.
Therefore the appropriate domain for this situation is all non-negative numbers:
Answer:
x < 8
Step-by-step explanation:
the dot isnt filled so symbol wont have a line under it
