Question 43182
{{{y = 2^(x - 1)}}}
There seems to be no limitations to the x-values, so Domain: {x|all real values}
Y-Intercept:
{{{y = 2^(x - 1)}}}
{{{y = 2^(0 - 1)}}}
{{{y = 2^(-1)}}}
{{{y = 1/2}}}
y-intercept: 0.5 .... so .... (0,0.5)
Answer: (A)
{{{ graph( 600, 600, -10, 10, -10, 10, 2^(x - 1) ) }}}
