Factor x²-16 (no spaces and use parenthesis) 

I must use complete the square when going from general to vertex

f(x) = x² + 10x + 21 ... what is the vertex?

write (x-4)²-6 in general form (no spaces and lowercase also use ^ as exponent)

If f(6)=3 and f(9)=6, is there a zero between them?

If f(6)=3 and f(9)=-6, is there a zero between them?

Are f(x)= x²-4 and f(x)=(square root of x) + 4 inverse?

Are f(x)= x/3 -4 and f(x)=3x+12 inverse?

Multiply (x²-4)(x+6) .... no spaces and use ^ for exponents

place in order for standard form

write x²-16x+5 in vertex from (no spaces)
