Which of the following exponential regression equations best fits the data shown below?
x −4 −3 −2 −1 0 1 2 3 4
y 0.05 0.20 0.75 2.25 10 30 100 350 1250
a.
y = 5.32 • 2.23x
b.
y = 3.14 • 4.98x
c.
y = 10.84 • 1.77x
d.
y = 8.46 • 3.51x

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
