The domain for the function f(x) = |x + 1| is the set of all real numbers.
The range of the function is the set of positive real numbers.
Given the function f(x) = |x + 1|
f(-4) = |-4 + 1| = | -3| = 3
This means that the number -4 is at a distance of 3 units away from -1 on the number line.
f(2) = |2 + 1| = |3| = 3
This means that the number 2 is at a distance of 3 units away from -1 on the number line.
f(1.5) = |1.5 + 1| = |2.5| = 2.5
This means that the number 1.5 is at a distance of 2.5 units away from -1 on the number line.

y=total amount of money
x=# of toppings
At JOES PIZZA
Large cheese- $0.25 per topping + base fee of $10
equation- y=0.25x+10
At SAMS PIZZA
Large Cheese- $0.50 per topping + base fee of $8
equation- y=0.5x+8
SYSTEM OF EQUATIONS
y=0.25x+10
y=0.5x+8
lets try 8 toppings first
y=0.25(8)+10
y=2+10
y=12
y=0.5(8)+10
y=4+10
y=14
8 does not work
lets try 1.5 topppings next
y=0.25(1.5)+10
y=0.375+10
y=10.375
y=0.5(1.5)+8
y=0.75+8
y=8.75
1.5 does not work
lets try 4 toppings next
y=0.25(4)+10
y=1+10
y=11
y=0.5(4)+8
y=2+8
y=10
4 does not work
finally 12 must work
y=0.25(12)+8
y=3+8
y=11
y=0.5(12)+8
y=6+8
y=14
we got y=11 for the first equation with 12 toppings y=11 for the first equation with 4 toppings
12+4=18
12 toppings at joes and 4 at sams i believe
