Question

Is there a website that could graph these for me? If not, can someone walk me though them? I fan and medal!
how is the graph of y= -2x²-5 different from the graph of y=-2x²

Answer 1

I'm sure there are tons of websites that can graph, but I recommend downloading geogebra since it's a very versatile graphing tool I use all the time

Answer 5

thanks @Luis_Rivera

Answer 6

Luis_Rivera, you forgot about the square exponent

Answer 7

so the graphs should be parabolas and not lines

Answer 8

Would that change the answer?

Answer 9

not really, you're still shifting down 5 units

just the overall shape will change, but the fundamental idea or transformation will not
