yes plug in 0 for x to find y intercept. The y intercept is (0,13)
Hi, again I am rusty at math (I haven't done it in two years). There are no solutions in my book for my homework, so could someone double check that I have the right idea?
1) Find the zeros of the given function f.
So, are the zeros x=2, x=-1, and x=0?
One more...
2) Find the x- and y-intercepts, if any, of the graph of the given function f. Do not graph.
For the X-intercepts I got...
(-7/2,0), (-3,0), (0,0)
How do I find the y-intercepts then? Do I plug in zero for "x"? If I do, wouldn't the y-intercept be just (0,0)?
Thank you so much in advanced!
Yay! Thank you! I'm so glad someone can point out my silly mistakes, haha.
The homework is going alright so far, but I'm a little uneasy that I have the correct way of doing this.
Find an equation of the line that satisfies the given conditions:
through the origin parallel to the line through (1,0) and (-2,6)
So my way of thinking was: find the slope since it is the same as the parallel line, and then the origin is at (0,0), correct? Thus...
plug it into the point-slope equation...
therefore the equation would be...(I hope)
Oh okay! Thanks!
HAHA yes that's what I get for my bad sleeping habits. That's meant to be y2 and x2...not squared. Sorry, I glanced over the formula super fast. Ignore that...
Anyway, I know you are sick of answering math problems. Maybe someone else will be able to help. I really hope I can get back into math in the next few weeks so I can figure things out on my own...
I just need explaining on this one:
"If C is an arbitrary real constant, an equation such as 2x - 3y = C is said to define a family of lines. Choose four different values of C and plot the corresponding lines on the same coordinate axes. What is true about hte lines that are members of this family?"
Do I plug in numbers for C? If I do, how do I solve that?
I was thinking to plug in numbers for x and y but I do not think it's asking that...
