Question

F(x)=x⁴+2x-3 найти f(0),f(-1),f(2)

Answer 1

F(x)=x⁴+2x-3
f(0)=0⁴+2•0-3=-3
f(-1)=(-1)⁴+2•(-1)-3=1-2-3= -4
f(2)=2⁴+2•2-3=16+4-3=17

Answer 2

To find the values of the function $f(x) = x^4 + 2x - 3$ at specific points, you simply need to substitute the given values of $x$ into the function and evaluate it.

1. $f(0)$: $f(0) = 0^4 + 2(0) - 3 = 0 - 3 = -3$

2. $f(-1)$: $f(-1) = (-1)^4 + 2(-1) - 3 = 1 - 2 - 3 = -4$

3. $f(2)$: $f(2) = 2^4 + 2(2) - 3 = 16 + 4 - 3 = 17$

So, $f(0) = -3$, $f(-1) = -4$, and $f(2) = 17$.
