Question

F(t)=t^2+1; Find f(-4t)

Answer 1

Answer:

$f(-4t)=16t^{2}+1$

Step-by-step explanation:

$f(t) = t^{2} +1$

In f(t) the variable is t, if you need to find f(something) it means you have to replace t for something. In this case you have to replace t for -4t.

$f(-4t) = (-4t)^{2}+1\\=16t^{2}+1$
