Hello,
y=k(x-1)²-9
and -6=k*1-9==>k=3
y=3(x-1)²-9
y=0==>3(x-1)²=9==>(x-1)²=3
==>x=1+√3 or x=1-√3
x-intercepts are (1+√3,0) (1-√3,0)

Answer:
-150
Step-by-step explanation:
If you do an= a+(n-1)d a(n) being similar to f(x) just a different variable. Where a(41)= 50+(41-1)(-5) i would say the 41st term in the sequence is -150 because the sequence is going down, I'm not positive, but I know the formula is right. a is the term similarly to f, n is similar to x it is the number of the term, and d is the constant which in this case is -5.
