Which function represents the graph of y=4x−1 ? q r s t four exponential curves graphed on a coordinate plane with horizontal x axis ranging from negative 5 to 5 in increments of 1. the vertical y-axis ranges from negative 3 to 7 in increments of 1. curve q begins above the x-axis in the second quadrant and passes through begin ordered pair 0 comma 2 end ordered pair and increases in the first quadrant. curve r is below curve q and begins above the x-axis in the second quadrant and passes through begin ordered pair 0 comma negative 0.25 end ordered pair and increases in the first quadrant. curve s begins below the x-axis in the third quadrant and passes through begin ordered pair 0 comma 1 end ordered pair and increases in the first quadrant. curve t is below curve s and begins below the x-axis in the third quadrant and passes through begin ordered pair 0 comma negative 1 end ordered pair and increases in the first quadrant.
