Question

F(x) = 2x - 5 при x = -2; -1; 0; 1; 2;​

Answer 1

1) f(x) = 2x - 5 при x = -2

f(x) = 2(-2) - 5= -4-5=-9

2) f(x) = 2x - 5 при x = -1

f(x) = 2(-1) - 5= -2-5=-7

3) f(x) = 2x - 5 при x = 0

f(x) = 2(0) - 5=-5

4) f(x) = 2x - 5 при x = -1

f(x) = 2*1 - 5= 2-5= -3

5) f(x) = 2x - 5 при x = 2

f(x) = 2*2 - 5= 4-5= -1

Answer 2

To find the values of the function F(x) = 2x - 5 at specific values of x, we substitute each x-value into the equation and calculate the corresponding output. Let's evaluate F(x) at x = -2, -1, 0, 1, and 2.

For x = -2: F(-2) = 2(-2) - 5 = -4 - 5 = -9

For x = -1: F(-1) = 2(-1) - 5 = -2 - 5 = -7

For x = 0: F(0) = 2(0) - 5 = 0 - 5 = -5

For x = 1: F(1) = 2(1) - 5 = 2 - 5 = -3

For x = 2: F(2) = 2(2) - 5 = 4 - 5 = -1

Therefore, the values of the function F(x) = 2x - 5 at x = -2, -1, 0, 1, and 2 are:

F(-2) = -9 F(-1) = -7 F(0) = -5 F(1) = -3 F(2) = -1
