All real numbers greater than or equal to -8. You can see 3 is a minimum point because at 3 the numbers start to increase again. -8 is the lowest number and the function is increasing as x approaches infinity starting at 3.
Well i did 6,000 and 5% and came out to 300 so maybe 300 a month or a week I’m not really sure
first you would multiply 25 x 3, which is 75 and then multiply 60 x 2 which is 120, then add 120 and 75 together, making the answer 195
It would be between the 3 m and the 4 m
hope this helps :)
