построим систему 2 функций
y=√x
y=3-2x
ответ x=1
график: https://umath.ru/calc/graph/?&func=sqrt(x);3-2x;
При а=0, т.к. получится 18+2*(0)^(x), а это выражение не имеет смысла
<span>1. y'=(x^5-2,5x</span>²<span>+3)'=5x^4-5x;
5x^4-5x=0;
5x(x</span>³-1)=0;
<span>x=0, x=1.
f(0)=0^5-2,5*0</span>²+3=3;
<span>f(1)=1^5-2,5*1</span>²+3=1-2,5+3=1,5.<span>
2. y'=(0,2x^5-4x^2-3)'=x^4-8x;
x^4-8x=0;
x(x</span>³-8)=0;
x-0, x=2.
f(0)=0,2*0^5-4*0²-3=-3;
f(2)=0,2*2^5-4*2²-3=-12,6.
