Answer:
This is an equation for a parabola. All parabolas are functions.
answer: function
Step-by-step explanation:
The given equation is

To solve for x, we have to subtract 8 to both sides

Now we need to get rid of -9 from the left side, and for that we do division


X equals to 48
The work is shown in the picture. I hope this helps.
Domain of f(x) = √6 - 2x is {x | -∞ < x ≤ 3}
Answer:
y=1/2x+9
Step-by-step explanation:
By the least steep graph, it means the "smallest" slope. The smaller the slope is, the less steep it'd be. The slope can be positive or negative, too.
1/4x<-1/2x<2x<-6x
Therefore, y=1/2x+9 would be the equation with the least steep graph.
I hope this helped! Have a good day!
