Answer:
Step-by-step explanation:
Given

Here, two functions are given that is
and 
Check for the intersection of the graph of two curves
From the graph, they cut at two different points i.e. 
Rest two roots are negative.
Answer:
f(2)=1
f(2) means that 2 is being plugged in for x so look for the y value when x is 2
in this case y is 1 when x is 2
Step-by-step explanation:
For this case, we decompose 240 into prime factors:
So, we have:
240 divided by 2
120 divided by 2
60 divided by 2
30 divided by 2
15 divided by 3
5 divided by 5
one
So, we have to, according to the right side of the decomposition shown:

Answer:

Here is the graph, it's just a line.
12 = 2*2*3
10 = 5*2
LCM = 5*3*2*2
= 15*4=60
the least common multiple is 60
