What is the range of this?

1 answer:

7 0

You have the correct answer. The answer is choice D) Set of real numbers less than -1. Nice job.

As x approaches negative infinity, then -3^x approaches 0 though never actually gets there. So overall, f(x) approaches -1 as x approaches negative infinity. Plugging in x = 0 leads to f(x) = -2 which supports choice D.

8 times as many as 8 is 64. A)8x8=64 B)64x8=8 C)8x64=8

Ivanshal [37]

Answer:
8*8 = 64 which is the first option

Explanation:
8 times as many as 8 means that we will repeat the number 8 for 8 times. This means that:
8 times as many as 8 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 = 8 * 8

This quantity is equivalent to 64.
Therefore:
8*8 = 64

Hope this helps :)
