Could you please check my work.

Determine whether the realtion is a funtion.

2.{(-6,2),(-2,5),(3,2),(3,-7)} -Not a function

2. Determine whether the equation defines y as a function of x.

2x+4y=15- the answer I got is y is a fucntion of x.

Evalute the function at the given value of the independent variable and simplify.

f(x)=2x^2-5x+6; f(x-1)- I got 2x^2-9x+13

Graph the given functions on the same retangular coordinate system. Described how the graph of g is realted to the graph of f.

f(x)=2x^2, g(x)=2x^2-3- Once I graphed it I got that g shifts the graph of f vertically down 3 units.
