Question

F(x)=-x+3x+1 найдите f(0) f(-5) f(4) f(a)

Answer 1

F(0)=0+3*0+1=1
f(-5)=5+3*(-5)+1=-9
f(4)=-4+3*4+1=9
f(a)=-a+3a+1=2a+1

Answer 2

To find the values of F(x) = -x + 3x + 1 for different inputs, simply substitute the given values into the function.

1. f(0): F(0) = -(0) + 3(0) + 1 F(0) = 0 + 0 + 1 f(0) = 1

2. f(-5): F(-5) = -(-5) + 3(-5) + 1 F(-5) = 5 - 15 + 1 f(-5) = -9

3. f(4): F(4) = -(4) + 3(4) + 1 F(4) = -4 + 12 + 1 f(4) = 9

4. f(a): F(a) = -(a) + 3(a) + 1 F(a) = 2a + 1

So, f(a) = 2a + 1
