Answer:
The correct option is A) {x | x = –5, –3, 1, 2, 6}
Step-by-step explanation:
Consider the provided diagram.
Here the left side represents the input (X) values and the right side represents the output (Y) values.
The domain refers to the set of possible input values.
Now consider the provided figure, the set of input value is:
{x | x = –5, –3, 1, 2, 6}
Hence, the correct option is A) {x | x = –5, –3, 1, 2, 6}
Answer:
x=1/3 or x=−2
if i can be brainliest that would be great
Step-by-step explanation:
Step 1: Add 2 to both sides.
3x^2+5x−2+2=0+2
3x^2+5x=2
Step 2: Since the coefficient of 3x^2 is 3, divide both sides by 3.
3x^2+5x/3=2/3
x^2+5/3x=2/3
Step 3: The coefficient of 5/3x is 5/3. Let b=5/3.
Then we need to add (b/2)^2=25/36 to both sides to complete the square.
Add 25/36 to both sides.
x^2+5/3x+25/36=2/3+25/36
x^2+5/3x+25/36=49/36
Step 4: Factor left side.
(x+5/6)^2=49/36
Step 5: Take square root.
x+5/6=±√49/36
Step 6: Add (-5)/6 to both sides.
x+5/6+ −5/6=
−5/6±√49/36x=−5/6±√49/36x=
1/3 or x=−2
