I have to write the definitions of all of these math terms, can you help me?
EastWind [94]

Answer:

Solution of an Equation in Two Variables - Generally, a two-variable system solution is an ordered pair that makes BOTH equations valid.

Graph of an Equation in Two Variables - In the Ax + By = C form, linear equations with two variables will appear, and the resulting graph is always a straight line.

Linear Equation - Any equation that can be written in shape is a linear equation. Ax+b=0, 0.0 Where the real numbers are a and b, and x is a vector.

Linear Function - Those whose graph is a straight line are linear functions. The following form has a linear function. F(x) = y = a + bx.

Find the range of the function for the domain {−3, 1, 4.5}.
Nitella [24]

Answer:

D. {4, 0, -3.5}

Step-by-step explanation:

domain (x) = {-3, 1, 4.5}

y= -x + 1

substituting domain/x-values into y= -x + 1

x= -3

y = -(-3) + 1

= 3+1

= 4

x= 1

y = -(1) + 1

= 0

x = 4.5

y = - (4.5) + 1

= -3.5

therefore, range ={4, 0, -3.5}
