given the equation y=-2x^2+4, calculate the corresponding y-cordinates for x=-3, -1, 0, 1, 3 show all work

Question

anonymous · Answer

@ x=-3 ,$$y= -2(-3)^{2}+4 = -14$$
@ x= -1 , $$y= -2(-1)^{2}+4 = 2$$
@ x= 0 , $$y= -2(0)^{2}+4 = 4$$
@ x= 1 , $$y= -2(1)^{2}+4 = 2$$
@ x= 3 , $$y= -2(3)^{2}+4 = -14$$

So when it comes to graphin this how do I know what is what.  I have to enter it into an ez graph application.  Which is x,y intercepts and then what is the x, y intervals

anonymous · Answer

i dont know what is the ez graph application .. but the y-intercept is the part of the y-axis that the function cuts , in which the abcissa of the point is 0 and the ordinate has a definite value , which means that when you substitute by x =0 in the function you get the y-intercept ,, and the x- intercept is the of the x-axis that the function cuts ,,,,,, and about the interval it means all possible values of X, that belongs to the domain , which have corresponding values in Y|dw:1327541395869:dw|
