The correct answer is B. 49 1/2
Answer:
The first one is 24, the secind one is 4 and the last one is 10
First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
We see that this function has a horizontal asymptote that crosses the y-axis at 2. This means that we can eliminate choices A and C.
From there, we can plug in values for points on the graph into the equation to see if they are true.
f(x)=6(1/3)^x+2
f(1)=6(1/3)^1+2
f(1)=2+2
=4 (Gives us the other coordinate)
f(x)=4(1/3)^x+2
f(1)=4(1/3)^1+2
=(4/3)+2
=3.33 (Does not give us the other coordinate)
Our correct answer choice is B

4a² − 20a + 25. is the answer.
