To solve this equation we have to factor.
We are looking for 2 numbers with a sum of -3, and multiplied they have to be -28. These numbers are -7 and 4.
So:
Answer:
897.23
Step-by-step explanation:
The decimal places start at the tenths:
00.tenths, hundredths, thousandths
So you would need to end up with only two numbers after the decimal.
To round, if a number is 4 or less, leave the next number as it is.
Ex: 2.32 → 2.3 Rounding to the tenths
78.614 → 78.6 Rounding to the tenths
If the number is 5 or higher, round up one number
EX: 37.76 → 37.8 Rounding to the tenths
6.389 → 6.4 Rounding to the tenths
Our number, 897.234, needs to be rounded to the hundredths place, so use the number to its right to determine the rounded value. The number 4 means that the hundredths place will remain the same, so the new value is:
897.23

Answer:
f(-3) = -6
Step-by-step explanation:
instead of f(x)
we have -3 replace x, so
f(-3)
then instead of x - 3,
we have
-3 - 3, which equals -6
Therefore, the answer is
f(-3) = -6
