-6.3, this is slope intercept form where it’s y=mx+b. M=slope of the line and b = the y intercept. You could also set x to 0.

Given the function h(x)=x^2-7x+6h(x)=x

Goryan [66]

Answer:

$0$ (no change)

Step-by-step explanation:

Recall that the average rate of change of a function $f(x)$ over the interval $[a,b]$ is equal to $\frac{f(b)-f(a)}{b-a}$ :

$\frac{h(b)-h(a)}{b-a}\\ \\\frac{h(6)-h(1)}{6-1}\\\\\frac{0-0}{5}\\ \\0$

Hence, the average rate of change of the function $h(x)$ over the interval $[1,6]$ is $0$ , or no change.

Add the following polynomials, then place the answer in the proper location on the grid.

aivan3 [116]

Answer:

$x^3 - 6x + 2$

Step-by-step explanation:

The given polynomials can be added together by adding like terms together as shown below:

=> Add together, the coefficient of all terms that have the power of 3.

$(2x^3) + (x^3) + (-3x^3)$

$2x^3 + x^3 - 3x^3$

$3x^3 - 3x^3$

$x^3$

=> $(-4x^2) + (6x^2) + (2x^2)$

$-4x^2 + 8x^2$

$4x^2$

=> $(6x) + (-8x) + (-4x)$

$6x - 8x - 4x$

$-6x$

=> $(-3) + (12) +(-7)$

$-3 + 12 - 7$

$2$

The answer = $x^3 - 6x + 2$
