I tried to answer the first one but I don't think that I have the right answer. I'm not sure about the other ones. Please show how to answer these. Thank you!
First one : Good job !!!!!
x^3 - 10x^2 + 24x
y intercept - easy - let x = 0 so y = 0
x ( x^2 - 10x + 24) = 0
x (x - 12) ( x + 2) = 0
Set each factor to 0 and solve for x and we get that x = 0 , x = 12 and x = 2
Hello there bro let me help you out,
I will do a problem for ou so you can figure it out!
As we can see we have f(x)=1/2 square root x-3
first thing that we need to do is find the zeros, which ill give you a hint, we have only 1 and it is displayed in the question.
that answer is the x-3 but the zero isnt -3 because we have to flip the sign which gives you 3 as your zero
now for the y intercept it isnt as simple
In fact I couldnt really find a Y intercept myself so I would have to say that there is either no Y intercept or that the intercept is 0.5
4x^4 - 17x^2 + 4
y intercept...let x = 0 so.....y = 4
(4x^2 - 1) (x^2 - 4) = 0
(2x + 1) ( 2x - 1) ( x + 2) ( x - 2) = 0
Set each factor to 0 and solve for x and we have that :
x = -1/2 x = 1/2 x = - 2 x = 2
