Answer: He is 18 years old right now.
Step-by-step explanation:
Let the present age of Ishaan be x
After 36 years,
his age will be x+36
According to question,
it is mentioned that Ishaan will be 3 times as old as he is right now ,
So, we will frame it in equation:
Hence, he is 18 years old right now.
Step-by-step explanation:
y = |x - 2| - 1
Given equation is in the form of y=|x-h|+k
Where (h,k) is the vertex
h = 2 and k =-1
So (2, -1) is the vertex for the given function
To find x intercepts we plug in 0 for y
we will get two values for x because of absolute function
0 = |x-2| -1
add 1 on both sides
|x-2| =1
x-2 =1 and x-2 =-1
x= 3 and x= 1
So x intercepts are (1,0) and (3,0)
the graph is attached below
