What is the value of the function y = 2x + 3 ⁢when x=−1 ?

y = 1

Step-by-step explanation:

In the equation y = 2x + 3, y is defined as  a function of a variable x. As such, the value of y changes as the value of x in a manner defined by the equation.

To get the value of y when x = -1, substitute -1 for x in the equation

y = 2 (-1) + 3

= -2 + 3

= 1

This means that where x = -1, y = 1.

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
