Graph  f(x)=2x+1 and  g(x)=−x+4 on the same coordinate plane.

What is the solution to the equation  f(x)=g(x) ?

x= ?

The table shows values for functions  f(x) and  g(x) .

What is the solution to  f(x)=g(x) ?

a. x= -2

b. x= -1

c. x= 0

d. x= 1

e. x= 2

Let  ​f(x)=−3/2x and  g(x)=(1/2)x−1

Graph the functions on the same coordinate plane.

What are the solutions to the equation  f(x)=g(x) ?

x = ___ or x= ___

Graph  f(x)=2x+1 and  g(x)=−x+4 on the same coordinate plane.

As shown they're equal when x = 1

What is the solution to  f(x)=g(x) ?

a. x= -2

b. x= -1

c. x= 0

d. x= 1

e. x= 2

c and e

As seen the intersect/ equal to one another at x = -2 and x = 0

Hope that helps!

f(x)  = 0.5x            g(x)  =  -0.5x  +  1

These intersect  when   x  =  0    and  x  = 1

Here's a graph :

First one

f(x)  =  2x  +  1     g(x)  =  -x + 4

If x  =  1.....then  y  =  3     so   (1,3)  is a solution

Here' the graph  :  https://www.desmos.com/calculator/kn7b69wttw

Julius has answered the last one.....see his graph....
