Question

dada f(y)=√x-16,calcule f(25),f(0) y f(7) y gráfico

Answer 1

f(y) = √x - 16 o √(x - 16)

⇒f(25)
f(25) = √x - 16
= √25 - 16
= 5 - 16
= -11 
f(25) = √(x - 16)
= √(25 - 16)
= √9
= 3

⇒f(0)
f(0) = √x - 16
= √0 - 16
= 0 - 16
= -16
f(0) = √(x - 16)
= √(0 - 16)
= √-16

⇒f(7)
f(7) = √x - 16
= √7 - 16
f(7) = √(x - 16)
= √(7 - 16)
= √-9
