Answer:
f(a) = a^2 + 2a + 1
Step-by-step explanation:
Given the function f(x)= x^2 +2x + 1, find: f(a):
Merely substitute ' a ' for x:
f(a) = a^2 + 2a + 1
If you really want e*f(a), multiply the above by e:
e*f(a) = ea^2 + 2ea + e
Option B seems to be the best answer.
If Jonas received a 30% off coupon, that means that the guitar is now at 70% of its original price (since 100% - 30% = 70%)
Thus, the best answer should be Option B since it’s the only one that works.

Answer:
Graphs 1, 2, and 3 are not functions. Graph 4 is a function.
Step-by-step explanation:
Use the vertical line test.
Imagine a vertical line moving from left to right.
If in any position of the vertical line, it intersects more than one point on the graph, then it is not a function.
In graphs 1 and 2 it is clear that there are many vertical lines than would intersect the graph at more than one point.
In graphs 3, a vertical line would intersect the vertical parts of the graph at more than 1 point, so graph 3 is not a function.
The only function is graph 4.
