Question

Function: g(x) = 2x2 – 8

Answer 1

Answer:

$q=0,\ r=2,\ s=3,\ t=-3$

Step-by-step explanation:

We must fill in the missing values in the table.

That is, we must find the values of q, r, s, t

Note that:

$q = d (-8)$   then we evaluate the function d at $x = -8$

$q =-\sqrt{\frac{1}{2}(-8)+4}$

$q =-\sqrt{-4+4}$

$q =0$

Note that:

$r = f(0)$   then we evaluate the function f at $x = 0$

$r =\sqrt{\frac{1}{2}(0)+4}$

$r =\sqrt{4}$

$r =2$

Note that:

$s = f(10)$   then we evaluate the function f at $x = 10$

$s =\sqrt{\frac{1}{2}(10)+4}$

$s =\sqrt{5+4}$

$s =3$

Note that:

$t = d(10)$   then we evaluate the function d at $x = 10$

$t =-\sqrt{\frac{1}{2}(10)+4}$

$t =-\sqrt{5+4}$

$t =-3$

finally:

$q=0,\ r=2,\ s=3,\ t=-3$
