2. Ifj(x) = x2 + 1, find j(a + 1).

Mathematics
1 answer:
DochEvi [55]3 years ago
5 0

Step-by-step explanation:

if you mean x multiply 2 :

j(x) = 2x + 1

j(a+1) = 2(a+1) + 1

= 2a+ 2 +1

=2a + 3

if you mean x to the power of 2

j(x) = x^2 +1

j(a+1) = (a+1)^2 + 1

= a^2 + 2a + 1 +1

= a^2 + 2a + 2

Geometry<br> What is the value of x to the nearest tenth?
Setler [38]

  x = (15.4)(4.7/7.7) . . . . multiply by 15.4

  x = 9.4

What is the domain of the function on the graph?
galina1969 [7]
Go to the left-most point on the graph. That point is (-3,-2). The x coordinate of this point is x = -3.

So the smallest x can be is x = -3. The variable x can't be any smaller. It can be larger than -3.

Since x can equal -3 or be larger, this makes the domain to be x \ge -3 (x is greater than or equal to -3)

In interval notation, you would write [-3, \infty)
The square bracket tells you to include the endpoint -3 while the curved parenthesis tells you to exclude infinity as an endpoint. Plus or minus infinity is always associated with a curved parenthesis.

In short, the answer is choice D
