Question 191051This question is from textbook
: Given f(x) = e^-2x + 1, evaluate the following. Round to the nearest ten-thousandth.
f(-1)
f(3)
f(-2)
Show your work here:
f(-1)=e -2(-1)+1=x-1
f(-1)=e^2+1
f(-1)=7.389+1
f(-1) = 8.389

Question 192060: This is the first time my instructor has presented problems written this way. I'm clueless. I would appreciate if someone could show me how to do this one so I can handle the rest. Thank you
If a is a positive real number, such that a is not equal to 1, and ax = b,
then the logarithmic function is represented as:
A) log a^x b = x
B) loga^b = f(a^x)
C) log b = x= a^x
D) loga^b = x

Question 192627: Can you help me please?
I can't post the graph but I can tell you the equation which is the graph of f(x)=log(x).
I have to find:
1.The description of transformation.
2. Vertical asymptote.
3. x intercept in (x,y)form.
Of this this equation, g(x)=-log(x)when graphed compared f(x)=log(x).

Question 192974: I need help with a few problems. I am stuck.
1) Write the equation (1/5)^-7 = 78125 in logarithmic form.
2) Simplify the expression (256x^4y)^1/4/(81xy^3)^3/4 Assume that all variables represent positive numbers
3) Find the value of x: log 3 27 = x
4) Assume that all variables are positive and multiply y^2/6(y^-2/6 + 8y^4/6)
Any and all help will be appreciated.
Thanks in advance!!
