The difference between the highest and lowest values in a data is called range. To find the range, first the highest and lowest values are found from data, then the lowest value is subtracted from the highest value.

In the above data,

Highest Value=71

Lowest Value=36

Range=Highest value-lowest value

=71-36

=35

Find f '(−4), if f(x) = (5x2 + 6x)(3x2 + 7). Round your answer to the nearest integer.

Rzqust [24]

$Use:\\(h(x)\cdot g(x))'=h'(x)g(x)+h(x)g'(x)\\\\h(x)=5x^2+6x\to h'(x)=(5x^2+6x)'=10x+6\\\\g(x)=3x^2+7\to g'(x)=(3x^2+7)'=6x\\\\f(x)=(5x^2+6x)(3x^2+7)\\\\f'(x)=(5x^2+6x)'(3x^2+7)+(5x^2+6x)(3x^2+7)'\\\\=(10x+6)(3x^2+7)+(5x^2+6x)(6x)\\\\\text{use distributive property}\\\\=30x^3+70x+18x^2+42+30x^3+36x^2\\\\=60x^3+54x^2+70x+42$

$\text{Put -4 instead of x into the expression}\\\\f'(-4)=60(-4)^3+54(-4)^2+70(-4)+42\\\\=60(-64)+54(16)-280+42=-3214$
