SOLUTION:
Case: Functions interval
Given: A function graph
Required: To find the region where the graph is increasing
Method:
The region where there is increase is where the graph has a positive slope, i.e. the region where the graph is moving from bottom left to top right.
We see the region on the graph as (-2, -2) to (2, 2)
Picking the x- axis only, this is (-2,2)
Final answer:
The final answer is (-2, 2)
Answer:
D.) 9√2
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 8^2 = √226^2
x^2 + 64 = 226
x^2 = 226 - 64
x^2 = 162
√x^2 = √162
√162 = √81 • √2
√81 = 9
√2 = √2
9√2
Answer:
x² - 20 = 0
Using the quadratic formula
a = 1 b = 0 c = -20
So we have
