Answer:
y = 2 * 9 ^ x
Step-by-step explanation:
From the first point, you can get the value of a, since any number with power 0 with always equal to 1
Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.
- 1458 = 2b ^ 3
- 729 = b ^ 3
- B = 9

Step-by-step explanation:
Answer: f(x) = -ln(x + 1) + 3
Step-by-step explanation:
We want it to be decreasing, then we can write it, for a start, as:
f(x) = -ln(x)
Ok, now we want it to have a positive y intercept, then we can add a real number inside the logarithm, and other outside: such that f(0) = positive number.
f(x) = -ln(x + 1) + 3
Now, when x = 0 we have:
f(0) = -ln(1) + 3 = 0 + 3 = 3
Then we have a decreasing logarithmic function, with an y-intercept larger than zero.
Answer:
A
Step-by-step explanation:
two real solutions! hope this helped!!
Solution
Find the mid point of A and B.
The mid point of A and B is (-1. 0.5)
Now find mid point of (0, 4) and (-1, 0.5)
= [(0 + (-1)/2 , (4 +0.5)/2 ]
= (-1/2, 4.5/2)
= (-0.5, 2.25)
The answer is (-0.5, 2.25)
Thank you.
