Any polynomial's graph cannot have two simultaneous maxima, so they must contain a minima between them. Thus, the total number of turning points of the graph is 3. Generally, when plotting a polynomial, the number of turning points is:
n = d -1; where d is the degree of the polynomial and n is the number of turning points. Thus, this function's degree must be at least 4. The answer is b.

tia_tia [17]

Answer:

i think the answer is Options B, C and E holds.

Step-by-step explanation:

this makes options B and C a choice:

Given the expression: 12x+18xy-24y

Factors of 12x=1,2,3,4,6,12 and x

Factors of 18xy=1,2,3,6,9,18,x and y.

Factors of 24y=1,2,3,4,6,8,12,24 and y.

next for E this is why its a choice:

12x+18xy-24y=6(2x+3xy-4y)

Solve for x:<br> x^2=a<br><br> If a&lt;0, then <br> If a=0, then<br> If a&gt;0, then
Anastaziya [24]

if a > 0, there are two possible solutions:

x^{2} = a\\\sqrt{x^{2} } = \sqrt{a} \\

the square root of a square is the base in absolute value bars

|x| = \sqrt{a}

x = -\sqrt{a} ; x = \sqrt{a}

if a = 0, that means x = 0. anything multiplied by 0 is 0

if a < 0, there are no solutions because anything squared has to be positive
