Find the slope of the function f ( x ) = 3 - 2 x , by the definition of limit.

musickatia [10]

Answer:

the slope is -2 $\lim_{n \to \0}( f(x+h)-F(x)) /h \\\\ \lim_{n \to \0} (3-2(x+h)-(3-2x))/h\\ f(x+h)= 3-2(x+h) \\f(x)=3-2x\\ \\\lim_{n \to \0} (3-2x-2h-3+2x)/h\\\\ \lim_{n \to \0} -2h/h\\ \\ \lim_{n \to \0} -2\\=-2\\\\In all limits, you have to put n goes to 0 (zero)$

Place these numbers in correct order and and simplify 25x^2 +6x^3 -7 +17 -24x^4 +6

Ket [755]

Answer:

$-24x^4+6x^3+25x^2+16$

Step 1:

We need to place the numbers in descending order of the power. Here, $-24x^4$ has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.

$-24x^4+6x^3+25x^2+17-7+6$

Step 2:

We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.

$17-7=10\\10+6=16$

Our final equation:

$-24x^4+6x^3+25x^2+16$
