Answer:

\frac{1}{10} (20x - 7x^2+30)

Step-by-step explanation:

13x-\frac{7}{10} x^2 -11x + 3

Combine liked terms

(13x-11x) -\frac{7}{10} x^2  + 3

2x - \frac{7}{10} x^{2} + 3

\frac{1}{10} (20x - 7x^2+30)

Identify the expressions for which limits exist.
Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Limits exist for:

\lim_{x \to4 \4} \frac{x^2 -x-12}{4-x} = \frac{(x-4)(x+3)}{4-x} = ( - 1 )( x + 3 ) = - 7

\lim_{x \to \ 2} \frac{x^2 +2x-8}{2-x} = \frac{(x+4)(x-2)}{2-x} = ( - 1 )( x + 4 ) = - 6

\lim_{x \to2 } \frac{x^2 +3x - 10}{x^2 -4} = \frac{(x+5)(x-2)}{(x+2)(x-2)} = \frac{x+5}{x+2} = \frac{7}{4}

If f(x)=3x + 2, find f(f^-1(14)).
dimaraw [331]

Answer:

f(x) = 3x + 2

x = 3f-1(x) + 2

x - 2 = 3f-1(x)

(x - 2)/3 = f-1(x)

(14 - 2)/3 = f-1(14)

12/3 = f-1(14)

4 = f-1(14)  

f(f-1(14)) = f(4)

f(4) = 3(4) + 2

f(4) = 12 + 2

f(4) = 14

A function and its inverse are inverse operations, like addition and subtraction. They undo each other.

f(f-1(x) = x
