Answer:
Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.
Step-by-step explanation:
They have the same exponent and it is multiplication.
There is a law of exponent that says .
So we have equals
.
Let's simplify (4*7)^(-2).
Since 4*7=28, we can say .
Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So .
Answer:
Step-by-step explanation:
Do what your instructions say: read the graph and solve.
1. In order to find x, you look for the point where g(x) is 4. That point is found where x = -2. (See the first attachment.)
Then 5x = 5·(-2) = -10. To answer the question, you need to find the value of g(-10). Look where the graph crosses the vertical line at x=-10. It is at y=0, so ...
... g(5x) = g(-10) = 0
2. You already found the answer to this when looking for the answer to the first question. g(x) = 0 when x = -10. (See the second attachment.)
