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:

This answer does not prove anything.
Answer:
Step-by-step explanation:
y=-1 ans.
x=2*-1=3
x=-2+3
x=1 ans.
Proof:
4*1-5*-1=9
4+5=9
9=9
i looks like it would be v
