Which of the choices below follow an exponential pattern? select all that apply. division of skin cells every half hour small graph of y+x^2 y= 4 times 3^x driving at a constant rate of 55 mph y=2x^3 graph x y 5 7 6 10 7 13 8 16

The correct answers are the division of skin cells every half hour and the equation
y=4(3)ˣ.

The division of skin cells can be modeled by the equation
y=a(b)ˣ, where a is the initial number of cells and b is the fraction they are divided into (half, fourth, etc.)
Since x is an exponent, this is exponential.

This is the same reason the equation is exponential; x is the exponent.

The second choice, y=x², would be quadratic, since x is raised to the second power.
Driving at a constant rate is linear, due to the constant rate of change.
y=2x³ is cubic, since x is raised to the 3rd power.
The table would be linear, since there is a constant rate of change (up 3 over 1, a slope of 3).
