Question
Question: If f(x) = \(2x + 3\), then \(x,f(x) = 0\)f(x) is...
If f(x) = 2x+3, then x,f(x)=0f(x) is
A
0
B
1
C
2
D
Does not exist
Answer
0
Explanation
Solution
f(0 – h) = limh→00−h=0
f(0 + h) = limh→0(0+h)2=0
If f(x) = 2x+3, then x,f(x)=0f(x) is
0
1
2
Does not exist
0
f(0 – h) = limh→00−h=0
f(0 + h) = limh→0(0+h)2=0
