Answer:
Since the independent variable x is not the exponent, does not represent an exponential function.
Step-by-step explanation:
The general expression of an exponential function is , where a > 0 and a ≠ 1
Now the given function is ..... (1)
So, we can say that the function f(x) = y is not an exponential function as x is not in power of any constant.
Therefore, since the independent variable x is not the exponent, does not represent an exponential function. (Answer)
Answer:
The size of Harry's loan is $9000.
Step-by-step explanation:
D(t) models Harry's remaining debt, in dollars, as a function of time t, in months that is given by :
We can see 200 is in negative that means it is getting deducted from the function. So, Harry must be paying this each month against his loan.
Lets put t = 0, that shows no payments have been made.
This will get the amount of loan, before any payments.
So,
Hence, the size of Harry's loan is $9000.
Answer:
If you look over the steps you can see that until 4x + x + 3 = 18, evertything is dandy. But the step after that 4x + x =21 seems a bit fishy.
Think about it they subtract 3 from both sides so the first side is correct
4x + x, but they added 3 to the other side:
not
4x+x = 21
Then we solve for 4x + x = 15
To solve for y we use :
y = x+3
y = 3+3 = 6
so (3,6) is the right answer
