AC = 28
Step-by-step explanation:
Answer:
A. Between 3.0 and 3.5 and between 4.0 and 4.5
Step-by-step explanation:
The zeroes of a function occur whenever a value of x returns zero. To predict where the zeroes lie, determine the interval(s) where the function crosses the x-axis. This occurs when either
goes from a negative value to a positive value or vice versa.
From
and
, the y-values go from 4.0 (positive) to -0.2 (negative), respectively. Therefore, there must be a zero in this interval.
From
and
, the y-values go from -0.8 (negative) to 0.1 (positive), respectively. Therefore, there must also be a zero in this interval.
Thus, the zeros of this function occur between 3.0 and 3.5 and between 4.0 and 4.5, leading to answer choice A.
The vertex is the highest point on a downward-opening parabola or the lowest point on an upward-opening parabola.
It is not direct variation because it does not follow the equation
y = slopex
THE points do not make the equation true .
