Answer:
It is in standard form because the exponents are in order from highest to lowest.
So this equation is in exponential equation format, which is
, with a = initial value (aka y-intercept) and b = growth/decay.
Looking at our equation, since 1 is in the a placeholder, this means that the <em>y-intercept is (0,1)</em>. Looking at our four graphs, the only graph that has (0,1) as the y-intercept is the third graph. Therefore, <u>the correct answer is the third graph.</u>
