Answer:
(d) f(x) = -x²
Step-by-step explanation:
For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...
f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)
f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)
Of the offered answer choices, the only one with a vertex at the origin is ...
f(x) = -x² . . . . . a=-1
Answer:
6.2 pints of white paint.
Step-by-step explanation:
9.7 is the sum of both paints used to pain her bedroom walls. If we know that 3.5 of the 9.7 was blue, we can safely assume that the remainder of the paint was white, thus 9.7 - 3.5 = 6.2
Answer:
If r-squared for the transformation is greater than r-squared for the original regression, the transformation is successful.
Step-by-step explanation:
If this is algebra, then you want to isolate the t. you need to subtract 1800 on both sides so then the expression would be 16t2= -1800. now you want to divide 16. t2= -112.5 then divide by 2 t= -56.25
