Answer:
<h2>3x+12=0</h2><h2>3x=0-12</h2><h2>x=-12/3</h2><h2>hence x=(-4)</h2><h3>✌️✌️ HOPE IT HELPS</h3>
Answer: Yes
Step-by-step explanation:
To solve this, imagine you have a vertical line. You can use a ruler or something straight. Move the ruler across the screen. Does the ruler intersect 2 points at once? If so, then it is not a function. If it only intersects one point, then it is a function.
Always remember: a function cannot have two x's with different y-values.
