Bonnie buys a used car for $2500. She calculates her average monthly expenses for gas, insurance, and maintenance at $150 per month. The function f(x) = 150x + 2500 represents her total cost of owning the car for x number of months. What is the domain for this situation? A. x ≥ 0 B. y ≥ 0 C. x ≥ 2500 D. y ≥ 2500 @amistre64
well, the independent variable defines the domian; so its going to be at least an x>= option
which one are you leaning towards?
D starts with a "y" so im going to go with a NO for that one
the x >= 2500 seems a bit outrageous to me, since x represents months owned.
Actually i would go with the answer B now that i look at it more
B starts with a y ... which is not even defined in the equation. My gut says A
yes, i agree one more question:)
