Funtion ! in vertex form is given by
<span>f(x) = 4x^2 + 8x + 1</span> = 4(x^2 + 2x + 1/4) = 4(x^2 + 2x + 1 + 1/4 - 1) = 4(x + 1)^2 + 4(-3/4) = 4(x + 1)^2 - 3
Thus, the least minimun value is (-1, -3)
Also, the least minimum value of function 2 is (-1, 0)
Therefore, function 1 has the least minimum value at (-1, -3)
Hi,
The answer is c. The sample is biased.
This is because the sample is taken on a single state, an Rebecca reports a statistic about the nation. Her data contains information only of her state. If she lives in a very cold state, there is probably more homeowners using electric heat than in a hot state.
42/60, x/320. 320/60=5.33333, 42*5.33333=224. So, about 224 students would ride the bus.
Answer:
As the described function, we want to find vertical asymtotes, we find the value of x so that the denominator is equal to 0.
Here, (x - 2)(x + 6) = 0
=> x = 2, x =-6
=> Option C is correct.
Hope this helps!
:)
