Answer:

Average rate of change: $-3$

Step-by-step explanation:

<u>Remember:</u>

The average rate of change of a function over an interval $[a,b]$ is $\frac{f(b)-f(a)}{b-a}$

<u>Given:</u>

$[a,b]=[1,7]$

$f(b)=f(7)$

$f(a)=f(1)$

<u>Calculation:</u>

$f(b)=f(7)=-(7)^2+5(7)+14=-49+35+14=-49+49=0$

$f(a)=f(1)=-(1)^2+5(1)+14=-1+5+14=4+14=18$

$\frac{f(b)-f(a)}{b-a}=\frac{0-18}{7-1}=\frac{-18}{6}=-3$

Therefore, the average rate of change of the function $g(x)=-x^2+5x+14$ over the interval $1\leq x\leq7$ is $-3$ .

Which expression is a difference of squares with a factor of 2x + 5? 4x2 + 10 4x2 – 10 4x2 + 25 4x2 – 25

Shtirlitz [24]

Answer:

4x^2 -25

Step-by-step explanation:

The other factor of the difference of squares is the "conjugate" of the given one: (2x -5). Then their product is ...

(2x +5)(2x -5) = (2x)^2 -(5)^2 = 4x^2 -25
