This is a sketch of the curve with the equation y=f(x) the curve has a minimum point at m(-1 -3)

Here's the solution ~

(i) y = f(x) - 2

The parabola will shift two units downwards !

therefore, the minimum point will be ~

(ii) y = f (2x)

Due to this change there will be no shift in position of the curve, therefore the minimum point remains same ~

(iii) y = 3 f(x)

The y - coordinate of lower point (vertex) will be 3 times the previous one ~ shifting downwards !

that is ~

i think it is c, not positive though

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
