F(x)=3x-2 and g(x)=x^2 find gf(x)
matrenka [14]

The value of the function g(f(x)) will be; (9x² -12x + 4).

<h3>What is a function?</h3>

Function is a type of relation, or rule, that maps one input to specific single output.

Given that the function are;

f(x)=3x-2 and g(x)= x²

Therefore, we need to find g(f(x))

Substitute x =3x - 2  into g(f(x)), that is;

g(f(x)) = g(x² )

g(f(x)) = (3x - 2)²

g(f(x)) = (9x² -12x + 4)

Therefore, the value of the function g(f(x)) will be; (9x² -12x + 4).

1. ABCD is a trapezoid with midsegment EF. If AB = 12 and CD = 24, what is the length of EF?
natali 33 [55]
For all of these answers, the equation used was (AB + CD)/2 = EF

1.12+24=36    36/2=18
2. 21 + 35 = 56    56/2 = 28
3. (7 + EF)/2 = 9 
    multiply by 2
   7 + EF = 18
   subtract 7
EF = 11

4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12
