You can put this solution on YOUR website!
1) suppose that g(x) = 5^x - 3.
\n" ); document.write( "a) what is g(0)?
\n" ); document.write( "g(0) = 5^0 - 3
\n" ); document.write( "any term with an exponent of 0 is equal to 1, therefore
\n" ); document.write( "g(0) = 1 - 3
\n" ); document.write( "g(0) = -2
\n" ); document.write( ":
\n" ); document.write( "b) What point is on the graph of g?
\n" ); document.write( "Let x = 2
\n" ); document.write( "g(2) = 5^2 - 3
\n" ); document.write( "g(2) = 25 - 3
\n" ); document.write( "g(2) = 22
\n" ); document.write( "Point 2, 22 is on the graph
\n" ); document.write( ":
\n" ); document.write( "c) If g(x) = 622, what is the value of x?
\n" ); document.write( "x = 622
\n" ); document.write( ":
\n" ); document.write( "2) Solve the logarithmic equation:
\n" ); document.write( "4e^(y+1) = 5
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "e^(y+1) = 5/4
\n" ); document.write( "e^(y-1) = 1.25
\n" ); document.write( "Using nat logs
\n" ); document.write( "ln(e^(y-1) = ln(1.25)
\n" ); document.write( "The log equiv of exponent
\n" ); document.write( "(y-1)*ln(e) = ln(1.25)
\n" ); document.write( "the ln of e is one so we have
\n" ); document.write( "y - 1 = .223
\n" ); document.write( "y = .223 + 1
\n" ); document.write( "y = 1.223
\n" ); document.write( "Check this on your calc: enter: 4*e^(1.223-1), results: 4.999 ~ 5
\n" ); document.write( ":\r
\n" ); document.write( "\n" ); document.write( "3) Write the given expression as a single logarithm:
\n" ); document.write( "21(log3)(third root of w)+(log3)(9w^2)-(log3)9
\n" ); document.write( "Assume you mean:
