f(x) will increase by 10 units
Step-by-step explanation:
The function f is defined by ; f(x) =5x -9
Forming a table for the function
x f(x)
-1 -14
0 -9
1 -4
2 1
Increasing x by 2 f(x) will be
x New x f(x)
-1+2 =1 1 -4
0+2=2 2 1
1+2=3 3 6
2+2=4 4 11
Change of value of f(x) will be
-4--14 = -4+14=10
1--9=1+9=10
6--4=6+4=10
11-1=10
The increase is 10, hence f(x) will increase by 10 units
