Alisiya [41]

$p(x)=2x^4-3x^2+x-1\\\\
Substitude\ p=-1\ into\ equation\\\\
p(-1)=2x^4-3x^2+x-1=2*(-1)^4-3(-1)^2-1-1=\\2*1-3*1-2=2-3-2=-3\\Answer\ p(-1)=-3$

Plz help me, I have others I need help with

lisov135 [29]

Step-by-step explanation:

That function is a line that goes through the origin (0,0).

You only need one more point to be able to draw it.

Take x=4,5 the corresponding value of y is exactly what you want to know, the number of miles the lava moved after 4,5 hours.

So y = 6 * 4,5 = 27

Your second point is (4,5 , 27).

Now you can draw your line.
