Given the definitions of f(x) and g(x) below, find the value of f(g(0)).

spayn [35]

Answer:

f(g(0)) = 45

Step-by-step explanation:

to evaluate f(g(0)) , evaluate g(0) then substitute the value obtained into f(x)

g(0) = - 3(0) - 3 = 0 - 3 = - 3 , then

f(- 3) = 2(- 3)² - 5(- 3) + 12

= 2(9) + 15 + 12

= 18 + 27

= 45

Multiple choice equation

Nat2105 [25]

★ QUADRATIC EXPRESSION ★

General standard quadratic equation -
$ax {}^{2} + bx + c = 0$
$x = \frac{ - b + - \sqrt{b {}^{2} - 4ac} }{2a}$

Comparing the coefficients -

a = 10
b = 3
c = -2

Hence the acquired quadratic is -

$10x {}^{2} + 3x - 2 = 0$
$or$
$2 = 3x + 10x {}^{2}$
Option B is correct
