Consider the table representing an exponential function .

Using the table, the exponential function is given by:

An exponential function is modeled by:

From the table, when x = 0, y = 8, hence the value of coefficient a is

When x = 1, f(x) = y = 4, and this is used to find coefficient b.

Hence, using the values found for coefficients a and b, the function is defined by:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
