Question

True or False?
The function f(x)=a^2 -4 will never cross the x-axis.

Answer 1

there is no \(x\) in \(a^2-4\)

Answer 2

oops! Sorry, I meant a^x

Answer 3

\(f(x)=2^x-4\) would cross the \(x\) axis if \(x=2\) since \(2^2-4=0\)

Answer 4

Then it is false, correct?

Answer 5

depends if there is any contsraints with the questions

Answer 6

constraints*

Answer 7

None that were mentions. All I was given was the statement: The function f(x)=a^x-4.

Answer 8

well then false would the the ideal choice

Answer 9

Thank you both
