we know that
The equation in vertex form of a vertical parabola is of the form
where
is the vertex of the parabola
and
is the axis of symmetry
if -----> open upward
if -----> open downward
In this problem we have
This is a vertical parabola open upward
The vertex is a minimum
therefore
<u>the answer is</u>
the vertex is the point
the axis of symmetry is
see the attached figure to better understand the problem
Answer: D. (3, -1)
Step-by-step explanation: its the only point that is in the line
In point slope form we are told the equation is y - 8 = (x - 4). To represent it as a function, we solve both sides for y, since y is written as a function of x, f(x).
y - 8 = (x - 4)
y - 8 = x - 4 parentheses are taken away since there's nothing outside
y = x + 4 add 8 to both sides
f(x) = x + 4 to rewrite with y = f(x).
Thus, the function f(x) = x+ 4 (first one) is the right representation.
Sorry i can't give you a model but you must plug in the numbers to find the answer.
T=1.25*14+4
T=17.5+4
T=21.5
Answer: yes.
