This needs to be broken down to find the y-intercept

After graphing, I found it was -3, but how do you find that besides graphing?

y = 2 ( x + 1/4)^2 - 25/8

Remember.....the y intercept point has an x value = 0.....so...let x = 0....and we have

y =2 (0 + 1/4)^2 - 25/8

y = 2 (1/4)^2 - 25/8

y = 2 (1/16) - 25/8

y = 1/8 - 25/8

y = -24/8 = -3 ....just as you found, LF !!!!

Thank you!! I get it!!
