104. Find the inverse g for each function f. a. f(x) = 1/2x-3

1 answer:

6 0

Change f(x) y to make it easier.
y = 1/2x-3
switch y and the x.
x = 1/2y-3
Add 3 to both sides
x+3 = 1/2y
Multiply both sides by 2.
2x+6 = y
Therefore, f^-1(x) = 2x+6

Write an equation for L in point slope form L is parallel to y=5x. points (1,-1)

mojhsa [17]

Answer:

Step-by-step explanation:

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

Parallel lines have the same slope.

We have y = 5x → m = 5.

The point-slope form:

$y-y_1=m(x-x_1)$

We have the slope m = 5 and the point (1, -1). Substitute:

$y-(-1)=5(x-1)\\\\y+1=5(x-1)$
