Step-by-step explanation:
60 is <u>66.67</u> percent of 90.
Take original price and multiply by .75. (An item that has been discounted 25% is 75% of the original price.) the number you get will be the sale price.
For this case what you should know is that both functions are of the potential type.
We have then that
y = 2 * 2 ^ x This function grows exponentially upwards.
y = -2 * 5 ^ x This function grows exponentially downwards.
