Answer 1

Ответ:

Объяснение:

f(-8) = 5*(-8)^2 = 5 * 64 = 320

f(-3) = 5 * (-3)^2 = 5 * 9 = 45

f(1) = 5 * 1 ^2 = 5

f(5) = 5 * 5^2 = 5 * 25 = 125

$\frac{320-45}{5+125} =\frac{275}{130} = \frac{55}{26} = 2,115 = 2,12$

Answer 2

Объяснение:

f(x)=5x^2

f(-8)=5×(-8)^2=5×64=320

f(-3)=5×(-3)^2=5×9=45

f(1)=5×1^2=5×1=5

f(5)=5×5^2=5×25=125

(f(-8)-f(-3)) / (f(1)+f(5))=

=(320-45)/(5+125)=275/130=2,12
