we know that
The exponential function is of the form
where
a is any value greater than
In General:
It is always greater than , and never crosses the x-axis
It always intersects the y-axis at
Its Domain is the Real Numbers
Its Range is the Positive Real Numbers
Examples
Let
1) For
2) For
3) For
4) For
therefore
the answer is the option
D.) exponential
<u>Answer-</u>
<u>Solution-</u>
Here, n represents the number of months and f(n) represents the number of laptops in the store after n months.
As the store had 150 laptops in the month of January or at the beginning.
So
Every month, 20% of the laptops were sold and 10 new laptops were stocked in the store.
As 20% of laptops were sold, so 80% were in the store.
So, after one month total number of laptops in the store,
Again after one month total number of laptops in the store,
Analyzing the pattern, the recursive function f(n) will be,

<h3>Answer : y = ⅚x - 3</h3>════════════════════
<h3>Known</h3>x1 = 6
y1 = 2
x2 = (-6)
y2 = (-8)

<h3>Question</h3>Equation of the line (y = mx + c)
════════════════════
<h3>Way to do</h3>#First, you find the gradient (m)
#Now use the formula of equation of the line
y - y1 = m(x - x1)
y - 2 = ⅚(x - 6)
y - 2 = ⅚x - 5
y = ⅚x - 5+2
y = ⅚x - 3
