>>>Assignment from last class is due if you did not turn it in (12 problems from last slide of Intro to Logs PowerPoint)

Problem a b h k asymptote(y=k)

point #1(h, a+k)

point #2(h+1,ab+k)

y= 3x-1

1) Fill in the table for the indicated problem and SKETCH a graph!

2) Find the inverse of f(x)=5x+3-1

OPEN NOTES QUIZ OVER INVERSES

Any quick questions before we begin?-Find inverse from a table-Find inverse from a graph-Find inverse from an equation

-Know when no inverse exists-Determine if an inverse is a function based on the graph (relationship with one-to-one)

RECALL…

When a variable is in the exponent, we rewrite as a logarithm in order to solve…
