Answer:
f(x)=ax2+bx+c
Step-by-step explanation:
The dolphin travels faster than the sea lion.
1- is they have distinct values
2- variables referring to x or y
hope this helps you out.
The answer would be B and Dbecause if you use the formula y-b=m(x-a) where m is the gradient, and (a,b) are a point on the line.
So m= (y2-y1)/(x2-x1) = (4-1)/(3-(-3)) = 3/6 = 1/2
And by using (a,b) this tells us that a=-3 when b=1 AND a=3 when b=4
Therefore the full equation must be either
y-1=1/2(x+3) AND
y-4=1/2(x-3)
Hope this helps :-)
Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have
so
therefore
f
(x)=f(-x) for all x in its domain.
Is a even function
