Question

Here is a table of values for y = f(x).

x 0 5 10 15 20 25 30 35 40
f(x) 5 6 7 8 9 10 11 12 13
Mark the statements that are true.
A. 5) = 6
B. The domain for f(x) is the set {5, 6, 7, 8, 10, 11, 12, 13).
O
C. The range for fx) is all real numbers.
D. f15) = 8​

Answer 1

A, D

Explanation:

for this table:

x 0 5 10 15 20 25 30 35 40

f(x) 5 6 7 8 9 10 11 12 13

A, assuming it's supposed to say f(5)=6, is true since 5 in x corresponds to 6 in f(x)

B is false, since the domain would be the set of all numbers in x, since domain corresponds to input (x) and range corresponds to output (f(x))

C is false, the range is not all real numbers since it is a defined set of numbers

D is true, since 15 in x corresponds to 8 in f(x)

Therefore, A and D are true
