Question

f(x)=x^2-6x-3

For x I got 3, but I am having trouble finding the y coordinate. Can someone please help?

Answer 1

for x you got 3? ...well okay remember f(x) is the same as y

so

y = x² - 6x - 3

just plug your 3 in for the x's

y = (3)² - 6(3) - 3
y = 9 - 18 - 3
y = -12

Answer 2

Ok I had that as far as the equation goes and plugging in 3, clearly my math is off when adding it all together! Thanks so much!

Answer 3

no problem :)
