f(x)=2(x+1)(squared)-18

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

f(x)=2(x-1)^2-18

x intercept is obtained when y=f(x)=0 . You have to solve f(x)=0

2(x-1)^2-18=0 <=>(x-1)^2=9 <=> x-1 = 3 or x-1=-3 <=> x=4 or x=-2

There are two x intercepts x=4 and x=-2

y intercept is when x=0

f(0)=-16

Finally vertex is (1,-18)
