Answer:
f(a + 1) = 3a + 4
Step-by-step explanation:
Given the function is:
f(x) = 3x + 1
To determine f(a + 1) we have to substitute (a + 1) in place of 'x'.
Therefore, we have:
f(a + 1) = 3(a + 1) + 1
= 3a + 3 + 1
= 3a + 4
['a' could be any real number.]
So, f(a + 1) = 3a + 4 is the answer.
The area of the given parallelogram is 120.
Step-by-step explanation:
Step 1:
The parameters needed to determine the area of a parallelogram are the base length and height.
The base length of this parallelogram is 15 inches while its height is 8 inches.
The area of a rectangle is determined by multiplying the base length with the height.
Step 2:
The area of the parallelogram 
Here the base length is 15 inches and the height is 8 inches.
The area of the parallelogram 
So the area of the given parallelogram is 120.
Answer:
The correct option is;
y = arcsinx and y = arctanx
Step-by-step explanation:
The given options are;
1) y = arcsinx and y = arccosx
Here, we have at the origin, where x = 0, arccosx ≈ 1.57 while arcsinx = 0
Therefore arccosx does not intersect arcsinx at the origin for it to be symmetrical to arcsinx or the origin
2) y = arccosxy and y = arctanx
Here arctanx = 0 when x = 0 and arcos x = 1.57 when x = 0 therefore, they are not symmetrical
3) y = arctanx and y = arccotx
Similarly, At x = 0, arccotx = 1.57 therefore, they are not symmetrical
4) y = arcsinx and y = arctanx
Both functions arcsinx and arctanx pass through the origin and their shapes are similar but inverted as they go from negative to positive.
