Answer choices Domain All Real Numbers Range y>0We're asked to graph y is equal to 5 to the X power and we'll just do this the most basic way we'll just try out some values for X and see what we get for y and then we'll plot those coordinates so let's try some negative and some positive values and I'll try to Center them around 0 so this will be my X values this will be my Y values let's start first with something reasonably negative but notThen the graph is So y = ( 1 / 3 ) –x does indeed model growth For the record, however, the base for exponential functions is usually greater than 1, so growth is usually in the form " 3 x " (that is, with a "positive" exponent) and decay is usually in the form " 3 –x " (that is, with a "negative" exponent)
