Question

how do I find the x and y intercepts of
f(x) = -2(x-3)(x-3) +1

Answer 1

if u want to find the x-intercept u put y=0 and if u want to find the y-intercept u put x=0

Answer 2

for the y intercept let x=0 then solve for y
-2(-3)(-3)+1
-18+1
-17

Answer 3

for the x intercept you have to foil the polynomials first then distribute the -2 then add 1

-2(x^2-6x+9)+1
-2x^2+12x-18+1
-2x^2+12x-17

Then use the method best suited for you in order to factor this down

Answer 4

i like to use the box method, less confusing less to worry about

Answer 5

for y=0 you get \[x=3\pm \sqrt{2}\div2\]

Answer 6

in this case box method is not the best but rather the quadratic formula
