f(x) = - 2x;

f(-1) = -2(-1);

f(-1) = 2

f(-1) = -2(-1);

f(-1) = 2

f(x) = -x^2 - x + 5, find f(-3)

f(-3) = -(-3)^2 - (-3) + 5

f(-3) = -9 + 3 + 5

f(-3) = -6 +5

f(-3) = -1

f(-3) = -(-3)^2 - (-3) + 5

f(-3) = -9 + 3 + 5

f(-3) = -6 +5

f(-3) = -1

1 Answer/Comment

3x – y = 2

y = 4x – 3

3x – (4x – 3) = 2;

3x - 4x + 3 = 2;

-x + 3 = 2;

-x = 2 - 3;

-x = -1;

x = 1;

y = 4(1) – 3;

y = 4 - 3;

y = 1

The solution set is (1, 1).

y = 4x – 3

3x – (4x – 3) = 2;

3x - 4x + 3 = 2;

-x + 3 = 2;

-x = 2 - 3;

-x = -1;

x = 1;

y = 4(1) – 3;

y = 4 - 3;

y = 1

The solution set is (1, 1).
