Answer: f(-3a-2)=-9a+13
Step-by-step explanation:
To find f(-3a-2), we plug in -3a-2 into f(x).
f(-3a-2)=3(-3a-2)+19 [distribute]
f(-3a-2)=-9a-6+19 [combine like terms]
f(-3a-2)=-9a+13
Now, we know that f(-3a-2)=-9a+13.
Rounding is when you have at least a two digit number (26 for example) and if the number the right (6) is 5 or above then the number goes up one unit, (therefore 26 becomes 27). But if the number (22) to the right is 4 or lower, then the number to the right stays the same, but the number to the right becomes a zero, (making 22 now 20).
