F(x) = x^2. What is g(x)?
2 answers:
Answer:
Step-by-step explanation:
is, in vertex form,
where h and k, the vertex, is (0, 0). It is positive because it opens upwards.
g(x) opens downward, so we know that it is negative. Because it is DOWN 4 units from the origin, is has been moved down -4. Putting that together, we can determine that the equation for g(x) is
, choice D in your list.

7. The formula is : 
and then 
and then 
.
The reason behind it is 14 is the least common multiple of 7 and 2 and 98 is the largest 2 digit multiple of 14. Subtract 98 and 14 and then divide by 14 to get 6 and then add 1. You will get 7 which is our answer!

Alright, lets get started.
When teh function is above the x axis, it is said to be positive.
When the function is below the x axis, it is said to be negative.
Now, looking at the graph provided with question, from -8 to -6, the function is above the x axis.
After -6, function goes below the x axis till -2.
In between -2 to 4, function again goes above x axis.
Means two times function goes above the x axis.
Between -8 to -6
Between -2 to 4
Hence there are two intervals where function is positive.
Hope it will help :)
