Tracey went shopping for a new back-to-school wardrobe. She spent $632.77 in her favourite stores and charged it all on a bank credit card. Over the course of the next seven months, she paid off her balance by making payments of $95.15 per month. Use a graphing calculator to determine the interest rate charged by the bank, compounded weekly.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the radius is 2 times the diameter.

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
