Answer:
The function has the property of exponential growth function.
Step-by-step explanation:
The exponential function is given by
, where b > 1.
Now, for x = 0, we get y = 1,
For x = 1, we get y = b
For, x = 2, we get y = b²
And so on.
Now, as b > 1, so, b² > b > 1 and the values of y are increasing as the value of x increases.
Therefore, the function has the property of exponential growth function.
Answer:
6471
Step-by-step explanation:
{a+c=529
{1.75c+2.25a=1118.75
{9a+9c=4761
-
{7c+9a=4475
2c=286
c=143
a=529-143=386
