Which graph represents the function of f(x) 9x^2 -36 / 3x + 6

Finger [1]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=\frac{9x^{2}-36}{3x+6}$

Remember that the denominator cannot be equal to zero

The value of x cannot be equal to x=-2

Simplify the numerator

$9x^{2}-36=(3x+6)(3x-6)$ ----> by difference of squares

substitute

$f(x)=\frac{(3x+6)(3x-6)}{3x+6}$

simplify

$f(x)=3x-6$

The domain is all real numbers except the value of x=-2

The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)

The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)

therefore

The graph in the attached figure

2 5/8 as a rational number ??

arlik [135]

Answer:

It's already a rational number?

Step-by-step explanation:

A rational number is any number that can be written as a fraction/ratio, and $2\frac{5}{8}$ is certainly a fraction. If you meant $2\frac{5}{8}$ as a decimal, then it'd be 2.625.
