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^25x+6; f(x1) I got 2x^29x+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^23 Once I graphed it I got that g shifts the graph of f vertically down 3 units.

Recheck the evaluate the function question.
