Question 6

The functions g is defined on the real numbers by g (x) = (x² + 1) (3x - 5). What is the value
of g(4) ?

-51

63

119

175

Answer 1

g(4) = 119

Explanation:

g(x) = (x² + 1) (3x - 5)

Substitute x for 4 in the equation

g(4) = (4² + 1) (3(4) - 5)

g(4) = (16 + 1) (12 - 5)

g(4) = (17) (7)

g(4) = 119

Hence, the value of g(4) is 119

Answer 2

Answer: 119

Explanation:

(4^2+1)(3*4-5)

=(16+1)(12-5)

=17*7

=119
