39
Step-by-step explanation:
5x3= 15
3x2=6
6x4= 24
24+15= 39:)
Answer:
<em>Exponential growth function</em>
Step-by-step explanation:
The table below represents some function between x and y:
x - 4 - 5 - 6 - 7
y - 15 - 90 - 540 - 3240
We are required to find if it's exponential growth, decay, or neither.
An exponential function is identified because each term is calculated as the previous term multiplied by a constant factor.
The values of x grow in increments of 1 and the values of x grow by a factor of 90/15 = 6, 540/90 = 6, 3240/540 = 6
Since there is a common factor and it's greater than 1, the function is exponential growth.
3-7p=-102
-7p=-102-3
-7p=-105
P=-105/-7
P=15
Hope this helps!
In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2
That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.
A<<<< answer.
