PLEASE PLEASE HELP ME (a) Using technology, determine the correlation coefficient for the data to the nearest hundredth. Explain the steps you used.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
