To find the inverse of the function ( f(x) = -3x + 21 ), we first replace ( f(x) ) with ( y ), giving us ( y = -3x + 21 ). Next, we solve for ( x ) in terms of ( y ): ( x = \frac{21 - y}{3} ). Finally, we switch ( x ) and ( y ) to express the inverse function: ( f^{-1}(x) = \frac{21 - x}{3} ).

What is the inverse -3x plus 5?
To write the inverse, you replace negatives with positives (and vice versa). Thus, for -3x + 5, it would be 3x - 5.
-3x equals -21 plus 4x?
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
What is 8x-4equlals 3x plus 21?

What is the x in the equation -x2 plus 3x plus 2y?
This is only half of an equation. If -x^2 + 3x +2y = 0, then x^2 -3x = 2y and y = (x^2-3x)/2 Solving for x is the inverse, but difficult without a second equation.
X plus 3x plus 5 equals 21?
x = 4
