Explanation:
How do you find a function for this story?
On your first day of work, you get $1. On your second day of work, you get $4. On your third day of work, you get $9. On your fourth day of work, you get $16. It continues this way for 30 days and then once you’ve completed the 30 days you receive a completion bonus of $500000.
No. of days Amount earned
1 1
2 4
3 9
4 16

30 500,000
To find a function to the story
Let
No. of days = d
Amount earned = A
When,
d=1, A=1
d=2, A=4
d=3, A=9
d=4, A=16
It can be seen that amount earned is a square of the number of days
Therefore,
The function for the story is:
A=d^2
When d=30
A=30^2
=30*30
=900
Adding the total earnings for 30 days=$500,000
That is
1+4+9+16+25+36+49+64+81+100+121+144+169+196+225+256+289+324+361+400+441+484+529+576+625+676+729+784+841+900=500000
