Answer:
f(x) = 2x + 4 domains {-1, 0, 1}
range {2, 4, 6}
(please mark brain if this helps and is correct)
Step-by-step explanation:
to solve f(x) to find the range you would want to input all the domain numbers in the equation f(x) to get the range of all the numbers you need
step 1: take the first domain number and input it into your equation where x is
ex: 2x + 4 [2(-1) + 4] = -2 + 4 = 2
step 2: add the second domain number and input it into your equation where x is
ex: 2x + 4 [2(0) + 4] = 0 + 4 = 4
step 3: add the last domain number and input it into your equation where x is
ex: 2x + 4 [2(1) + 4] = 2 + 4 = 6
Now we have determined what the range is
Answer:
x + 3

Step-by-step explanation:
ratio means over so,
<u>1</u><u>0</u><u>0</u><u> </u>= <u>n</u>

500
n=1
Take -5x + y =13 and rearrange for y:
y=13+5x
Substitute into other equation for y:
-3x+3(13+5x)=3
Multiply out brackets:
-3x+39+15x=3
Simplify:
12x+39=3
Rearrange for x:
12x=-36
x=-3
Substitute back into y=13+5x:
y=13+5(-3)
y=13-15
y=-2
