If the curve `y=ax^(1//2)+bx` passes through the point (1,2) and lies above the x-axis for `0lexle9` and the area enclosed by the curve, the x-axis, and the line x=4 is 8 sq. units. Then

If the curve y=a x^(1/2)+b x passes through the point (1,2) and lies above the x-axis for 0lt=xlt=9 and the area enclosed by the curve, the x-axis, and the line x=4 is 8 sq. units, then (a) a=1 (b) b=1 a=3 (d) b=-1

If the curve y=ax^((1)/(2))+bx passes through the point (1,2) and lies above the x-axis for 0<=x<=9 and the area enclosed by the curve, the x-axis,and the line x=4 is 8 sq.units, then a=1 (b) b=1a=3 (d) b=-1

Let the curve y= ax^((1)/(2)) +bx passes through the point (1,2) and lies above the axis for 0lt xlt 9 .If the area enclosed by the curve the x-axis and the line x =4 is 8 eq. units Then-

The curve u=a sqrtx+bx passes through the point (1, 2) and the area enclosed by the curve, the x - axis and the line x = 4 is 8 sq. units. Then

The curve y = a sqrt(x) + bx passes through the point (1,2) and the area enclosed by the curve the x-axis and the line x = 4 is 8 sq. units. Then

If the curve y=ax^(2)+bx+c passes through the point (1, 2) and the line y = x touches it at the origin, then
