For what values of k does the graph of y=-2x^2+5x+k not cut the x-axis?
i want the working out to be detailed on how exactly do we solve this question.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

is there more to this question?
