Answer:
f(4) = - 1
Step-by-step explanation:
To evaluate f(4) substitute x = 4 into f(x) , that is
f(4) = 5(4 - 7) + 14 = 5(- 3) + 14 = - 15 + 14 = - 1
All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
<h3>How to graph the inequality on a number line?</h3>
The inequality expression is given as:
2x+2/x+7 >= 0
Multiply both sides by x + y
2x+2 >= 0
Subtract 2 from both sides
2x > -2
Divide both sides by 2
x >= -1
Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
See attachment for the number line of x >= -1
