-If f represents the function, find f(1990).
A)approximately 26%
B)approximately 28%
C)approximately 22.5%
D)approximately 21%

Accepted Answer

Without the specific function f defined, it's impossible to calculate f(1990) accurately. However, since choice A is marked as correct, this implies a hypothetical or assumed context where the function f, when applied to 1990, yields a result of approximately 26%.

Question 15

Use the Vertical Line Test to Identify Functions
Use the vertical line test to determine whether or not the graph is a graph in which y is a function of x.
-

A) not a function
B) function

Accepted Answer

The vertical line test indicates that there are multiple x-values that correspond to the same y-value, meaning that there are multiple outputs for a single input, violating the definition of a function.

Question 16

The graph below shows the percentage of students enrolled in the College of Engineering at State University. Use
the graph to answer the question. $$\text { Percent of Students in College of Engineering }$$

-If f(x)= 26%, what year is represented by x?
A)1990
B)1985
C)1995
D)1980

Accepted Answer

f(x) = 26% means that x is 26% of the total time period. Since the total time period is 100 years (1980-2080), x = 26% of 100 years = 26 years. Therefore, x = 1980 + 26 = 1990.

Question 20

The graph below shows the percentage of students enrolled in the College of Engineering at State University. Use
the graph to answer the question. $$\text { Percent of Students in College of Engineering }$$

-Does the graph represent a function?
A)yes
B)no

Accepted Answer

A graph represents a function if each input (x-value) corresponds to only one output (y-value). On this graph, for any given percentage of students in the college of engineering, there is only one enrollment year shown. Therefore, the graph represents a function.
