Answer:
• zero: -4, -4/3, 7
• positive: -4 < x < -4/3 . . . or 7 < x
• negative: x < -4 . . . or -4/3 < x < 7
Step-by-step explanation:
Zeros of the function are at x=-4, -4/3, +7. These are the values that make each of the individual factors be zero. For example, x-7=0 when x=7.
The function will be negative for x-values left of an odd number of zeros. It will be positive for x-values left of an even number of zeros (including left of no zeros, which is to say right of all zeros). This is because the sign of the factor giving rise to the zero changes for x-values on either side of that zero. (This is not true for zeros with even multiplicity, as the sign does not change at those.)
Your vertex would be (3,4)
Answer:
$31.80
Step-by-step explanation:
Since it is indicated that the sum of three consecutive odd integers is at most 216 and not exactly 216, the largest possible value of one of these integers is 73. The answer for this question would be option C. 69, 71, and 73 are the consecutive odd integers. Hope this answers your question.
