Answer:

A. y = 3x + 3

Step-by-step explanation:

Slope = change in y / change in x

From 3 to 5 (x) = +2

From 12 to 18 (y) = +6

slope, m = 6/2 = 3

Using point slope form

y - y1 = m (x - x1)

y - 12 = 3 (x - 3)

y - 12 = 3x - 9

y = 3x -9 + 12

y = 3x + 3

What are the domain restrictions of the expression g2−7g+10g3−6g2+8g ? Select each correct answer.
Sauron [17]

Answer with Step-by-step explanation:

We are given that an expression

f(g)=\frac{g^2-7g+10}{g^3-6g^2+8g}

We have to find domain restriction of the given function.

f(g)=\frac{(g-5)(g-2)}{g(g-4)(g-2)}

Domain restriction means : It is that value of x when substitute in function then  function will  not defined.

It means it is that values which makes denominator zero.

From given function we can see that

When substitute g=0 then it makes denominator zero.

Hence, the function is not defined at g=0

Substitute g=4

Then, it makes denominator zero.

Hence, function is not defined  at g=4

Substitute g=2

Then,it  makes denominator zero.

Hence, function is not defined  at g=2

Therefore, the function is defined for all values of g except g=0, g=2 and g=4
