finding the x intercept

Tutor: None Selected Time limit: 1 Day

When Given the vertex and the y intercept of the parabola , use (y-k)=a(x-h)^2 where a=0 

Find the X intercept of the parabola with vertex (1,1) and y intercept (0,3) write your answers in this form (x2,y2) , (x2,y,2)

Thank you for the opportunity to help you with your question!


given (h, k ) = (1,1)

put the values 


now put the values from other point (0,3)


2 = a

put the value of a in parabola equation


for x intercept y=0



-1 = 2 (x^2 +1 -2x)

-1/2 =  (x^2 +1 -2x)

x^2 +1 -2x +1/2 = 0

x^2-2x+1.5 = 0 

solve it by using quadratic formula

you will get values of x which are x = 1+0.707i and 1-0.707i 

so the answer for x intercept are

(x2,y2) = (1+0.707i , 0)

(x2,y2) = (1- 0.707i , 0)
