Which facts are true for the graph of the function below? Check all that apply. F(x) = log6 x
2 answers:
Answer:
A and C are true
Step-by-step explanation:
Given:
We need to graph the log function. Please see the attached file for graph.
Domain: x>0 All real number greater than 0.
Range: All real number.
y-intercept: Put x=0 and solve for y. (Does not exist)
y-intercept: Put y=0 and solve for x. (1,0)
Log function is increasing function.
A is true. (It is increasing)
B is False. (Because Range is all real number)
C is true. (x-intercept (1,0))
D is false. (It is decreasing.)
E is false. (The y-intercept is (0, 6))
F is false. (Domain is x>0)
Hence, A and C are true.

Answer:
Option (c) is correct.
Step-by-step explanation:
Given equation is :
The equation can be solved for a as follows :
Step 1.
Cross multiply the given equation
Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c
The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".
