Showing all variables are positive, use properties of logarithms to write the expression as a sum or difference of logarithms or multiples of logarithms log2 9x

the answer to this question is "motor unit"

the answer is b.)

< 1=< 2

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
