If f(x) = x/2=-3 and g(x)=3x^2+x-6,find (f+g)(x)

Wewaii [24]

(f+g)(x) is 3x^2 + 3x/2 - 9

(f+g)(x)=f(x)+g(x)=x/2-3+3x^2+x-6= 3x^2 + 3x/2- 9

If 6 pounds of grapes costs $1.89, how much would 15 pounds of grapes cost?

Alja [10]

So divide 1.89 by 6 to see how much would one pound of grape be
1.89/6=0.315
Then multiply 0.315 (price for one pound of grape ) by 15
0.315*15 =4.725 $for 15 pounds of grape

Which of the following statements are true about the equation below?

emmasim [6.3K]

Answer:

Option 1, 2, 5 are the correct answer.

Explanation:

We have the quadratic equation, $x^2-6x+2=0$

First derivative of the equation is given by 2x - 6 = 0

So x = 3

At x = 3 the value of quadratic equation is extreme, corresponding y is given by $3^2-6*3+2=11-18=-7$ , So extreme value is at (3,-7)

Second derivative of the quadratic equation is given by 2 ( positive value)

Second derivative is positive so graph of equation has a minimum value.

Now root of the equation $x^2-6x+2=0$ is given by

$\frac{6+\sqrt{(-6)^2-4*1*2}} {2} =3+\sqrt{7}$

$\frac{6-\sqrt{(-6)^2-4*1*2}} {2} =3-\sqrt{7}$

Option 1, 2, 5 are the correct answer.
