Step-by-step explanation:
Standard form of a quadratic is f(x) = ax² + bx + c.
To convert to vertex form, the simplest method is to find the x-coordinate of the vertex using h = -b/(2a).
Then, plug back into the equation to find the y-coordinate of the vertex. k = f(h).
Finally, the leading coefficient is the same as the standard form, a.
f(x) = a(x − h)² + k
Another method is to complete the square.
Answer:
Step-by-step explanation:
√20=√5*2*2
√20=2√5
G(-2) = 8(-2) -2 = -16 - 2 = -18
g(4) = 8*(4) - 2 = 32 - 2 = 30
as you can see 30 is greater than -18 so the answer is C
Answer: 9.6
Step-by-step explanation: A rational number can be written as a ratio of two integers (9.6 can write as 96/10)
