1 5/8 as a decimal is equal to 1.625 :)
1/4 would go in between 0&1, -1.2 would go in between -1 & -2, square root of 5 would go in between 2&3, pi would go in between 3&4.
The domain of a function is the numbers on the x coordinate that the function can be. The range is the same, but for the y axis. So for the function you gave, if the domain is all numbers between -1 and 3, you plug in those numbers.
4-9x+14x>32 do the exponents
5x>28 combine terms and subtract 4 from both sides
x>5 3/5 divide by 5 on both sides
Hope this helps
Brainliest is always appreciated : )
