Answer 2

Correct Question

If f(x) = 3x³ - 4x² + 2x + 4. Then find the value of g(2).

Answer

• The value of g(2) = 16.

Given

• A cubic polynomial 3x³ - 4x² + 2x + 4.

To Do

• To find the value of g(2).

Step By Step Explanation

Given a cubic polynomial 3x³ - 4x² + 2x + 4. We need to find the value of g(2).

By substituting the value

Substituting the value of x = 2.

$\longmapsto \sf3 {x}^{3} - 4 {x}^{2} + 2x + 4 \\ \\ \longmapsto \sf3 {(2)}^{3} - 4 {(2)}^{2} + 2(2) + 4 \\ \\\longmapsto \sf (3 \times 8 )- (4 \times 4) + (2 \times 2 )+ 4 \\ \\ \longmapsto \sf24 - 16 + 4 + 4 \\ \\\longmapsto \sf 32 - 16 \\ \\\longmapsto \underline{ \boxed{ \green{\bold{ 16}}}} \: \: \: \: \bigstar$

Therefore, the value of g(2) = 16.
