Answer:
Yes, the given table represent an exponential function.
Step-by-step explanation:
Given table is :
x y
1 4
2 16
3 64
4 256
Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function .
We see that y-values are basically powers of 4 so we can write the related function as .
Which is clearly in form of .
Hence yes, the given table represent an exponential function.
Answer:
1. y = 9(x+1/2)^2 -13/4
Step-by-step explanation:
y = 9x^2 + 9x – 1
first isolate the x terms
y = 9(x^2 +x) -1
then add 1/4 inside the brackets to make it a perfect square trinomial (half of the coefficient of the x term squared is how we get 1/4)
since we just added 1/4 we need to subtract what we just added to balance the equation. so 1/4 times 9 is 9/4 ( the number we just added to the equation). then you subtract 9/4 outside of the brackets.
y = 9(x^2 +x +1/4) -1 -9/4
then simplify
y = 9(x+1/2)^2 -13/4

Answer:
C
Step-by-step explanation:
Keep a consistent ratio of 4:2, and we need a total of 36 glasses of punch.
So if the ratio 4:2 is a total of 6, then we would need 6 times the amount because 6*6 is 36. So 4 and 2 * 6 or 6 (4+2) = 24+12. So the answer is C.
