Help please!!!!!!!!!!!!! Explain if possible

Answer is C.
For every option, sub in the value and find the answer that matches the equation!

Example for option A, F(x) = x + 4 and G(x) = x²
G(F(x)) = G(x + 4) ーー> sub in the value of F(x)
Let's take the subbed in value, (x + 4) as x, and this x will be the x for G(x).

∴ Since G(x) is x²
G(x + 4) = (x + 4)² ーー> remember (x + 4) is represented as x.
= x² + 16
∴ You know that the answer is not A, do this for all options and you'll find the answer, C!

What is (14x^2– 27x+9) / (7x-3)? A. 7x-3 B. 2x-3 C. -211x+9 D. 2x-33

Yakvenalex [24]

Answer:

B. 2x - 3

Step-by-step explanation:

$\rm \frac{ {14x}^{2} - 27x + 9}{7x - 3}$

$\rm = \frac{ \cancel{(7x - 3)}(2x - 3)}{ \cancel{7x - 3}}$

$\boxed{ \rm \bold{= 2x - 3}}$

The function f(x) is a quadratic function and a limited table of values is provided below. Write the equation of the quadratic p

OverLord2011 [107]

Answer:

f(x) = 3x^2 -21x +36

Step-by-step explanation:

The table gives the x- and y-intercepts, which are sufficient to write the equation in factored form. The x-intercepts of 3 and 4 tell you that factors are (x -3)(x -4). When x=0, this product is (-3)(-4) = 12, but the y-intercept value is 3 times that: 36. So, the factored equation is ...

f(x) = 3(x -3)(x -4)

Multiplying this out, we get ...

f(x) = 3(x^2 -7x +12)

f(x) = 3x^2 -21x +36
