PLEASE PLEASE HELP PLEASE THANK YOU I REALLY NEED IT PLEASE !!!! This table shows values represented by an exponential function
What is the average rate of change for this function for the interval from x=1 to x=3 A)12 B)6 C)24 D)9

Answer:
It seems to be D)9 from intervals 1 to 3...
Step-by-step explanation:
Can't really explain that well, but the rate of change in an exponential function should always be decreasing or increasing. Instead of it being constant like a linear equation.
I.E. Not additive, instead to find it we need to divide.
So, it should be 9. However, It does not seem to be maintained for the values after 3. Oh well!
Hope this helps!

Answer:
D'G' = 52.5 units
Step-by-step explanation:
Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5
D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )
G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )
Calculate D'G' using the distance formula
d =
with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)
D'G' =
=
=
=
= 52.5 units
