False.
An exponential growth is a function of the form:
y = A (b) ^ (k * t)
Where,
k> 0
b> 1
Because the value of b> 1 means that the function grows.
Therefore, the answer to the question is false, because if k = 2 but b <1 then the function decreases.
Answer:
False
Let, the numbers = x,y
Now, x + y = 38
x - y = 50, x = 50 + y
Substitute it into first equation,
50 + y + y = 38
2y = 38 - 50
y = -12 / 2
y = -6
Substitute it into first equation,
x - 6 = 38
x = 38 + 6 = 44
So, your final answer is x = 44 & y = -6
