The axis of symmetry for the graph of the function f(x)=3x^2+bx+4 is x= 3/2. what is the value of b
Papessa [141]

Answer:

b = -9

Step-by-step explanation:

The function is given as :

f(x)=3x^2+bx+4

The axis of symmetry for this function is x = 3/2

It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

x=\dfrac{-b}{2a}

Putting x = 3/2 and a = 3 we get :

b=-2ax\\\\b=-2\times 3\times \dfrac{3}{2}\\\\b=-9

So, the value of b is -9.

Welp lol &lt;3 find the value of x that makes j||k
alukav5142 [94]

Answer: C. 42

Step-by-step explanation:

(3x + 3) is the same angle as 129.

So, you have to equal them to each other.

3x + 3 = 129

Now you solve.

Subtract 3 from each sides.

3x = 126

Divide 3 from each side.

x=42
