Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (- 4, - 9) into the partial equation

- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7

y = $\frac{1}{2}$ x - 7 ← equation of line

Find the inverse of f(x)=−3/2x+7/2.

timama [110]

Answer: $f^{-1}(x)=-\frac{2}{3}x+\frac{7}{3}$

Step-by-step explanation:

To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.

$y=-\frac{3}{2}x+\frac{7}{2}$ [replace y with x and x with y]

$x=-\frac{3}{2}y+\frac{7}{2}$ [subtract both sides by 7/2]

$x-\frac{7}{2} =-\frac{3}{2}y$ [multiply both sides by -2/3]

$-\frac{2}{3} (x-\frac{7}{2} )=y$ [distribute]

$y=-\frac{2}{3}x+\frac{7}{3}$

Now, we have our inverse function.

$f^-^1(x)=-\frac{2}{3}x+\frac{7}{3}$
