Which is the interval notation represent the domain?
Kazeer [188]

Answer:

The first choice, (-\infty, 7) \cup (7, \infty).

Step-by-step explanation:

The dashed vertical line is a vertical asymptote. The x-coordinate of all points on this vertical asymptote are equal to 7. In other words, when the x-value of a point on the graph approaches 7, its y-value approaches infinity (or negative infinity.)

Either way, the graph is not defined for x = 7. The point 7 should thus be excluded from the domain of the graph.

The graph is apparently defined for all other x-values. The domain of the function should thus be all real numbers with the exception of x = 7. Here's how to write that in interval notation:

  • The set of all real numbers can be expressed as the interval (-\infty, \infty). Note that infinity \infty (or (- \infty) itself isn't a real number. The round brackets indicate that both endpoints are excluded from the from the interval.
  • The set of all real numbers less than (not equal to) 7 is (-\infty,7 ) (both ends are excluded.) The set of all real numbers greater than (not equal to) 7 is (7, \infty).
  • The set of all real numbers that is not equal to 7 is the union of all real numbers less than 7 and all real numbers greater than 7. The union operator \cup connects two intervals.

In other words, the domain is (-\infty, 7) \cup (7, \infty).

What is the equation of the line that has a slope of -3 and passes through the point (4,6)?
garri49 [273]

Answer:

y = -3x + 18

Step-by-step explanation:

y = mx + b

m = -3

6 = (-3) * 4 +b

b = 6 - (-3) * 4

b = 6 +12

b = 18

y = -3x + 18

Find f(-1) given f(x)=-3x^3+2x^2+24<br><br> Help me please
Talja [164]
Answer: 23

If x=-1 then (-1) to the power of 3 = -1 and (-1) to the power of 2= 1

3(-1)^3= -3
2(-1)^2= 2
-3+2+25= 23

3) k(a)= a + 4; Find K(0) ; k(2x - 7)
Westkost [7]

Answer: k(0) = 4; k (2x - 7) = 2x -3

Step-by-step explanation:

If k(a) = a + 4

K(0) will be 0 + 4

K(0)= 4

Then, k (2x - 7) = 2x -7 +4

K (2x - 7) = 2x - 3
