Answer:
G. 477.75
Step-by-step explanation:
Use the point-slope form of the equation of a line:-
y - y1 = m(x - x1)
y - 4 = 4(x - 2)
y - 4 = 4x - 8
4x - y = 4 is the answer
Use the formula
for quadratic trinomial. Then you can form from a quadratic trinomial perfect square:
.
From the last given step you have that
.
Since 5·16=80, you can substitute the previous expression for perfect square into function expression and get:
.
This means, when x=-4, f(-4)=-80 and vertex has coordinates (-4,-80).
Answer: correct choice is C.
