Write an equation for each exponential function in the form y=abₓ (to the xth power)

- through the points (0,2) and (3,1458)

Respuesta :

whatever929

Answer:

y = 2 * 9 ^ x

Step-by-step explanation:

From the first point, you can get the value of a, since any number with power 0 with always equal to 1

  • 2 = a(1)
  • a = 2

Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.

  • 1458 = 2b ^ 3
  • 729 = b ^ 3
  • B = 9
