PLEASE HELP ITS URGENT What are the domain and the range of this graph?

The domain is {x∈ℝ∣∣x≤0} and the range is {y∈ℝ∣∣y≤0}.

The domain is {x∈ℝ∣∣x≤0} and the range is {y∈ℝ∣∣y≥0}.

The domain is {x∣∣x∈ℝ} and the range is {y∈ℝ∣∣y≤0}.

The domain is {x∣∣x∈ℝ} and the range is {y∈ℝ∣∣y≥0}.

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

Peter applied to an accounting firm and a consulting firm. he knows that 30% of similarly qualified applicants receive job offers from the accounting firm, while only 20% of similarly qualified applicants receive job offers from the consulting firm. assume that receiving an offer from one firm is independent of receiving an offer from the other. what is the probability that both firms offer peter a job?
