What is a quartic function with only the two real zeros given?
2 answers:
Answer:
The correct option is A.
Step-by-step explanation:
It is given that a quartic function has only two real zeros.
The degree of quartic function is 4. The function has only two real roots, therefore the roots has their multiplicity.
Put -1 and -4 for x. If the value of f(x)=0 at x=-4 and x=-1 then the function have two zeros -4 and -1.
Put x=-1
Put x=-4
Therefore option A is correct.
The value of y is 2 at x=-1 and 512 at x=-4, therefore option B is incorrect.
The value of y is -2 at x=-1 and -512 at x=-4, therefore option C is incorrect.
The value of y is -9 at x=-1 and -9 at x=-4, therefore option D is incorrect.

Answer:
Raymond was for 29 minutes on the trampoline.
Step-by-step explanation:
We are given the following in the question:
Total cost of session = $43.25
Entrance fee = $7
Cost per minute = $1.25
Let t be the minutes that Raymond was on the trampoline.
Thus, we can write
Total cost =
Entrance fee + cost per mute(minutes that Raymond was on trampoline)
Putting the values, we get,
Thus, Raymond was for 29 minutes on the trampoline.
Answer:
Equation of function, y = (x-1)²
Step-by-step explanation:
The general formula of a parabola symmetric about x - axis is given by (x-h)²=4a(y-k), where (h,k) is the vertex.
Here (h, k) = (1,0)
So, we have (x-1)²=4a(y-0)
(x-1)²=4ay
One point on the parabola is (0,1) since y intercept is 1.
Substituting
(0-1)²=4 x a x 1
1 = 4 a
Equation of parabola,
Equation of function, y = (x-1)²
