Without graphing, determine whether the function represents exponential growth or exponential decay. Then find the y-intercept. A. Exponential growth; 4
B. Exponential decay; 4
C. Exponential growth; 0
D. Exponential decay; 5

I will give brainliest to the correct answer!

Exponential decay; 4

Step-by-step explanation:

This represents exponential decay, because the number which is being raised to the power x is less than one. This means that as x increases, y decreases.

The y-intercept occurs when x is equal to zero. When x = 0, we have , so the y-intercept is 4.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
