Substitute the x for the value of x do the problem to see if the result is the value of y

ivettef365 · Answer

For example you have 2x^2 -3, when you plug 0 it works because the result is -3,when you plug 1 for x then you ha 2-3 = -1, it works, when you plug 2 then you have 8-3=5

thank you

ivettef365 · Answer

what about when you use 2x-3, with 0 it works because you have 0-3= -3,  when you plug 1, then you have 2-3=-1, but when you plug 2, then you have 4-3= 1, then does not work
