Question

The table shows values for functions f(x) and G(x)

What the known solutions to F(x) = G(x)
Select each correct answer
1
3
7
9
11

Answer 1

Answer: 3

Explanation:

Since, if there are two functions then the solution of these function is a value for that which the functions give the same value,

By the given table,

f(3) = -9

g(3) = - 9

⇒ f(3) = g(3)

⇒ For x = 3, both f(x) and g(x) are giving the same value (-9)

⇒ The solution of the system of these function is 3.

⇒ Second option is correct.

Answer 2

The answers are 3 and 7.

Explanation:

We have given the table of values of f(x) and g(x).

We have to choose the value of x when f(x) = g(x).

when x = 1

f(x) = 1 ≠ 3 = g(x)

when x = 3

f(x) = -9 = g(x)

when x = 5

f(x) = 0 ≠ -2 = g(x)

when x = 7

f(x) = 2 = g(x)

when x = 9

f(x) = 12 ≠ 9 = g(x)

when x = 11

f(x) = 11 ≠ 1 = g(x)

Hence, the answers are 3 and 7.
