What is the domain of the function on the graph?
Dennis_Churaev [7]

Answer:

All real numbers greater than or equal to -3

Step-by-step explanation:

First look at graph where the line points to which direction of the graph

And look for any closed or open circles in the graph

Since in the graph has a close circle at (-3,-2) meaning it includes that x-value for its domain.

With the graph going to positive infinity it states that the domain is all real numbers.

So in conclusion it has a domain of all real numbers greater than or equal to -3

if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?
umka2103 [35]

Answer:

(p - q)(x) = (x -1) (x - 4)

Step-by-step explanation:

Given

p(x) = x^2 - 1

q(x) = 5(x - 1)

Required

(p - q)(x)

This is represented as:

(p - q)(x) = p(x) - q(x)

(p - q)(x) = x^2  - 1 - 5(x - 1)

(p - q)(x) = x^2  - 1 - 5x + 5

Collec like terms

(p - q)(x) = x^2  - 5x + 5 - 1

(p - q)(x) = x^2  - 5x + 4

Expand

(p - q)(x) = x^2 -4x - x + 4

Factorize

(p - q)(x) = x(x -4) - 1(x - 4)

(p - q)(x) = (x -1) (x - 4)
