Hope this are right I have great day! Take care!シ❤︎
Answer:
A. f(x) = x²
Step-by-step explanation:
Observing the values
when x= -2..............f(x)= 4..................this is x²............-2²= 4
when x= -1..............f(x)= 1......................this is x²............ -1² = 1
when x= 0..............f(x)=0.....................this is x².......... 0²= 0
when x= 1.............f(x)= 1........................this is x²........ 1²= 1
When x=2........... f(x) = 2...................... this is x²........ 2² = 4
⇒The first option is correct.
A "true proportion" is when you know for a fact the equations are equivalent. You can easily multiply or divide without doing any work.
Step-by-step explanation:
the slope of the line is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
the trick in such a situation is to find good points on the chart that are crossed by the line. and by "good" I mean points with round integer coordinates.
I see 2 such points :
(-2, 3) and (0, -3)
x changes by +2 (from -2 to 0)
y changes by -6 (from 3 to -3)
the slope is -6/+2 = -6/2 = -3
