<span>A table representing a function is provided below.
x 1 2 3 4 5
y 1 16 64 256 1,024
According to the data in the table, from x = 2, the value of y can be represented as

which is equivalent to

This indicates an exponential function.
Thus, the </span><span>most accurate description of the function's graph is: "The graph initially appears flat but ascends sharply."</span>
Answer:
0.69 miles per hour
Step-by-step explanation:
speed = distance/time
speed = 506/723
506/723 = 0.69
1/2x + y = 3
Rearrange the equation to achieve the slope-intercept form. (y=mx+b)
1/2x + y = 3
Eliminate 1/2x from both sides.
y = -1/2x + 3
The y-intercept (where the line intersects the y-axis) is three, and the slope (the change in y over the change in x) is -1/2.
Hope this helps!
