Jaolin likes to go cycling. The diameter of her bike wheels is 75cm. She invented a counter that keeps track of the number of revolutions the
wheels make. If the counter shows 30 revolutions, how far has Jolin
traveled?

understand that i don't know the answers

will someone answer his question

a is the correct

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
