Explain how to use a graph of the function f(x) to find f(3)

2 answers:

8 0

Given a function f(x), the value of x is the x-coordinate on the x-axis. Therefore, if we wanted to find f(3) given the graph of f(x), we look for the point on the graph where x = 3, then find its y-value. That y-value is the answer to f(3).

This also applies for any other value of x.

Answer:

For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

Answer:

I am pretty sure the answer is 498.

Step-by-step explanation:

You have to solve the parentheses first. So,

9(7 (14-6) -3 x 2)

63 (8) -6)

63(8)-6

63(8) = 504

504-6 = 498

please let me know f this is correct :)

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y [1st Equation]: -10x = -7x + 6
[Addition Property of Equality] Add 7x on both sides: -3x = 6
[Division Property of Equality] Divide -3 on both sides: x = -2

Step 3: Solve for y

Substitute in x [2nd Equation]: y = -10(-2)
Multiply: y = 20

How can you check that this answer is correct? 5,244 = 6= 874

nignag [31]

I think you meant 5,244 ÷ 6 = 874.

Answer/Step-by-step explanation:

We can check if this 5,244 ÷ 6 = 874 is correct by doing it opposite.

Since it 5,244 divide 6 we can do 874 x 6.

$\left[8 7 4] \\$

× $[6]$

======

+ 5244

=======

5244

Hence, this answer is correct.
