Find the function value, if possible.

Question

q(t) = (4t2 + 5)/t2

(a) q(2)

(b) q(0)

(c) q(−x)

Answer 1

All you need to do is to substitute the given value for t to get the function value so

q(2) =( 4 x4) +5 divided by 4= 21/4= 5 1/4

q(0) is undefined since the denominator would be 0

q( -x) =( 4x^2 +5)/x^2
