Answer:
The right answer is option 3.
lim x → −3 f(x) = [infinity] means the values of f(x) can be made arbitrarily large by taking x sufficiently close to (but not equal to) −3.
Step-by-step explanation:
The limit of a function is a fundamental concept concerning the behavior of that function near a particular input.
A function f assigns an output f(x) to every input x. We say the function has a limit L at an input a: this means f(x) gets closer and closer to L as x moves closer and closer to a. More specifically, when f is applied to any input sufficiently close to a, the output value is forced arbitrarily close to L.
That is,
lim x → a f(x) = L

Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5
Answer:
$0.085 per mile or 8.5 cent per mile
Step-by-step explanation:
We know:
Total expenses = $1837
Gasoline expense = Total expenses - other expenses
= 1837 - 972 - 114 - 105 = $646
Benito drove in total of: 7600 miles
Cost of gasoline per mile = Money spent for gasoline / total miles
= $646 / 7600
= $0.085 per mile or 8.5 cent per mile
Hope this helped :3
