put this function in graphing calculator
And if you don't have a graphing calculator, then calculate it out bu yourself:
(x + 1)(x − 1)(x − 7) = 0
We can solve
this problem by using the formula:
1 +
fractional increase = (original employees + new employees) / original employees
Lets say,
x = original
employees
Therefore
substituting the known values:
1 + 0.05 = (x
+ 30) / x
1.05 x = x +
30
0.05 x = 30
x = 600
Therefore
the number of employees working now is:
<span>x + 30</span>
<span>= 630
employees</span>

y = 5500 ln (9t+4)
y is the number of mowers sold
t is the number of years
Substitute 2 in for t to find the number of mowers sold after 2 years
y = 5500 ln (9*2+4)
= 5500 ln (18+4)
= 5500ln(22)
