Question

The domain for which the functions defined by f(x) = 6x^2 + 1 and g(x) = 11-
7x are equal is​

Answer 1

Answer:

Step-by-step explanation:

f (x) = g (x)

6x² + 1 = 11 - 7x

6x² +7x -10 = 0

6x² + 12x - 5x -10 =0

6x(x+2)-5(x+2) = 0

(6x-5)(x+2)=0

∴, $x= \frac{5}{6} , -2$

Thus domain x = {  ${\frac{5}{6},-2}$ }
