How do I create a quadratic equation that passes through the points (-1,2),(1,7),(4,5)?

Let t=50 y=30(2.7)^-0.004t y=30(2.7)^-0.004(50) y=30(2.7)^-.2 Need help with proper technique for using TI-83 to calculate. Thanks

log[3](2x+8)+log[3](3x)=log[3](2) Need help with this one please, thanks.

f(x)=(7x+28)/(x-3) and g(x)=(3x+28)/(x-7) Find: (fog)(x) (gof)(x) (fog)(-1)

1.)Find inverse function of the function f(x)=(x+3)+9 2.)Find the inverse of the function r(x)=3x-6/5x+3 thanks

log((x(sqrtã(X^2+1)/(x+1)^(2/3)))^6 Any ideas would be great, thanks

Use properties of logartithms to simplify and solve. Thanks. ln(x-3)-ln(11x-23)+in(x-1)=0

e^x-2-12^2x+3=0

e^(x-2)-12^(2x+3)=0 Class is a college level math prep. Sorry for previous post being incomplete. I'm thinking: ln^(x-2)=ln12^(2x+3) (x-2)ln=(2x+3)ln12 xln-2ln=2xln(12)+3ln(12) xln-2xln(12)= 2ln+3ln(12) and not sure

The function f(t)=100,000/1+5000e^(-t) represents the population of an endangered species bird t years after they were introduced to a non-threatening habitat. a.In what year will there be 70,000 birds? b.How many birds were intially introduced to the hab...

A newly married couple decides to keep having children until they have a girl. What is the probability that the couple will have at least 5 children?

The answer is correct for 1 which is C. However for Ques 2. it says which element so the answer should be B

that should be x times the square root of x squared plus one divided by( or fraction bar) x plus one raised to the 2/3 power, all raised to the power of 6

I believe it may be x=2,x=13

e^(x-2)-12^(2x+3)=0 Class is a college level math prep. Sorry for being incomplete in the post.

Never mind and thank you
