Which statement is true ? Help plzzzz

Mathematics

Zarrin [17]4 years ago

Answer:

Correct choice is B

Step-by-step explanation:

The quadratic function g(x) has equation g(x)=ax^2+bx+c. Find values of a, b and c:

g(0)=2=a\cdot 0^2+b\cdot 0+c\Rightarrow c=2.

g(2)=3=a\cdot 2^2+b\cdot 2++2\Rightarrow 4a+2b=1.

g(4)=2=a\cdot 4^2+b\cdot 4+2\Rightarrow 16a+4b=0.

From the last equation b=-4a and 4a-8a=1,\\ \\a=-\dfrac{1}{4},\\ \\b=1.

The equation of the quadratic function g(x) is

g(x)=-\dfrac{1}{4}x^2+x+2. This quadratic function determines the parabola with vertex at point (3,2). Thus,

1. The maximal value of f(x) is 4 at x=2.

2. The maximal value of g(x) is 3 at x=2.

Thus, the maximal value of f(x) is greater than the maximal value of g(x). So option B is correct.

I hope this helps you



area formula=pi.r^2


1) Area=3,14. (3,5)^2


Area=38,465


Area nearest 38,5


2) Circumference=2pi.r


Circumference=2.3,14.3,5


Circumference=21,98


Circumference nearest 22

Simplify 8 - {x - (5 + x)}. 3 13 -2x + 3 -2x + 13
love history [14]
<span>Simplify 8 - {x - (5 + x)}:

Order of operations rules require that you perform work inside parentheses first.  Thus, do this first:   </span>x - (5 + x)         =>  x - 5 - x   =>   -5.  

Now we have the following:           8 - {-5}    =>   8+5   = 13 (answer)

Please note:   To avoid confusion, please separate answer choices, such as <span>3 13 -2x + 3 -2x + 13, by using commas or by putting each choice on its own new line:

</span><span>3
13
-2x + 13
I was and still am unsure of what you meant here.</span>
