Q. Is (5,1) a solution to the equation y=−3x2+4x?Choices:(A) yes(B) no
Substitute x value: First, we need to substitute x=5 into the equation y=–3x2+4x to see if y equals 1.Calculation: y=–3(5)2+4(5)=–3(25)+20=–75+20=–55.
Calculate y: Now, we compare the calculated y-value with the y-coordinate of the point (5,1).Since –55 does not equal 1, (5,1) is not a solution to the equation.
