Let f(x) = -2x + 7 and g(x) = -6x + 3. Find (f o g) and state its domain.

1 answer:

3 0

$(f\circ g)(x) = -2(-6x+3) + 7 = 12x - 6 + 7 = 12x + 1$

The domain is all real numbers as a composition of two linear functions have no restrictions (all linear functions have domain of R)

x2.y2. x1 y1

$m = \frac{y2}{x2}-\frac{y1}{x1}$

$m=\frac{3}{0}- \frac{2}{4}$

= 1/-4

slope = 1/-4
