Use the equations and the graph to solve the problem.
1 answer:
The value of function f(3) + g(3) will be 9. Then the correct option is E.
<h3>What is a function?</h3>Functions are found all across mathematics and are required for the creation of complex relationships.
Use the equations and the graph to solve the problem.
f(x) = 2x − 1
g(x) = 3x − 5
Then the addition of the functions f(x) and g(x) will be
f(x) + g(x) = 2x − 1 + 3x − 5
f(x) + g(x) = 5x − 6
When x = 3, then the value of function f(3) + g(3) will be
f(3) + g(3) = 5(3) − 6
f(3) + g(3) = 15 − 6
f(3) + g(3) = 9
Then the correct option is E.
