Is the sentence true or false?
Constant functions have horizontal lines as graphs.
True
False
Which of the following is a constant function?
f(x)=x3f(x)=x^3f(x)=x3
f(x)=10f(x)=10f(x)=10
g(x)=3xg(x)=3xg(x)=3x
f(x)=5f(x)=5f(x)=5
F(x)=3xF(x)=3xF(x)=3x is constant function.
f(x)=∣x∣f(x)=|x|f(x)=∣x∣
f(x)=−3f(x)=-3f(x)=−3
g(x)=9g(x)=9g(x)=9
f(x)=5x+1f(x)=5x+1f(x)=5x+1
2
f(x)=x2f(x)=x^2f(x)=x2
f(x)=3f(x)=3f(x)=3
g(x)=6g(x)=6g(x)=6
f(x)=2x+1f(x)=2x+1f(x)=2x+1
Constant functions are neither increasing nor decreasing.
Constant functions are always decreasing.
It is done.
