3x+4x+5x=54
12x=54
x=4.5

Plug in the value of x into all three segments.

AB= 3*4.5= 13.5
BC= 4*4.5= 18
AC= 5*4.5= 22.5

What is the range of the function f(x) = 3x2 + 6x – 8?
Fudgin [204]

Answer:

Range → {y| y ≥ -11}

Step-by-step explanation:

Range of a function is the set of of y-values.

Given function is,

f(x) = 2x² + 6x - 8

By converting this equation into vertex form,

f(x) = 3(x^2+2x-\frac{8}{3})

     = 3(x^2+2x+1-1-\frac{8}{3})

     = 3[(x+1)^2-\frac{11}{3}]

     = 3(x+1)^2-11

Vertex of the parabola → (-1, -11)

Therefore, range of the function will be → y ≥ -11
