Answer:
f(-3)= -3
Step-by-step explanation:
We are given the function:
f(x) = 2x+3
and asked to find f(-3). Essentially, we want to find f(x) when x is equal to -3.
Therefore, we can substitute -3 for each x in the function.
f(x)= 2x+3 at x= -3
f(-3)= 2(-3) +3
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction
Multiply 2 and -3.
f(-3) = (2*-3) +3
f(-3)= (-6)+3
Add -6 and 3.
f(-3)= (-6+3)
f(-3)= -3
If f(x)= 2x+3, then<em> f(-3)= -3</em>

• Given the table of values, you can identify these points:

If you plot them on a Coordinate Plane, you get:
As you can observe, it is a Linear Function.
• The equation of a line in Slope-Intercept Form is:

Where "m" is the slope of the line and "b" is the y-intercept.
In this case, you can identify in the graph that:

Therefore, you can substitute that value and the coordinates of one of the points on the line, into this equation:

And then solve for "m", in order to find the slope of the line.
Using this point:

You get:

Therefore, the equation for the data in Slope-Intercept Form is:

Hence, the answer is:
• It represents a Linear Function.
