Help please please please xx
with what
Here is a suggestion. Use technology to graph them. Then apply the vertical line test.
graph all the equations and then do vertical line test if the line intersects the graph more than 1 then the equation doesn't represent a function
Okay let me graph them
Okay so here is my graph
and I think the answers are c and d?
for example this the vertical line intersects the graph 2 times so it's not a function when line intersects 2 times that means x values are repeating
I think b and c?
because they look like they are functions
Use the vertical line test (If a vertical line goes through the curve more than once, it's not a function) also, you know lines y= mx and parabolas, y = x^2 are functions
if you see a y^2, that is a clue it's not a function
So b and D?
yes. when you draw a line on A ,C graph you will see the line intersects the graph more than once
So are those the only and final answers?
yes y=x^2-2 and y=6x represents the function
Thank you so much
