$$x=2y^2+5$$

anonymous · Answer

this is similar to the one we just did but alittle confused...... 0.o   
help @whpalmer4

anonymous · Answer

ok can the domain and range be 
$$-5\le x \le 5  $$   &   $$-5 \le y \le 5$$ ????

whpalmer4 · Answer

okay, have you figured out what the graph looks like?

whpalmer4 · Answer

that's going to tell you what conic section, too

anonymous · Answer

um no i dont know how to graph these??? 
sorry it took so long for me to get back to you and my computer kept glitching

Okay, make yourself a table with two columns, x and y.  Pick some values for x.  Write them in the table.  Calculate the values of y that go with them.  Write them in the table as well.  Now break out the graph paper and plot those points.  What does the graph look like?

anonymous · Answer

ok what plots do i use. please give me a example

anonymous · Answer

lol points

Our equation is $$x = 2y^2+5$$

For this it's easier to use y as the dependent variable, so I'll do that.

y = -2, x = 2(-2)^2+5 = 
y = -1, x = 2(-1)^2+5 = 
y = 0, x = 2(0)^2+5 = 
y = 1, x = 2(1)^2+5 =
y = 2, x = 2(2)^2+5 =
