Answer:
x = -7
Step-by-step explanation:
Our function is . Notice that our possible roots are when x + 4 = 0 and when x + 7 = 0. So, our roots are -4 and -7.
However, the power above x + 4 is even, meaning the graph will simply <em>touch</em> the x-axis at x = -4, but not pass through. The power above x + 7, though, is odd, which means the graph will <em>cross</em> the x-axis.
Thus, the answer is x = -7.
Answer:
<h2>800%</h2>
Step-by-step explanation:
Let p represent the population
in 1965 → the population becomes 2p
in 1970 → the population becomes 2(2p) = 4p
in 1975 → the population becomes 2(4p) = 8p
p ——————> 100%
8p ————-—-> x%
then
