The function is given by the formula y = 2x + 4. Find: a) the value of y if x = 1 b) the value of x if y = 0 c) does the graph of the function pass through the point A (0, -2)
y = 2 * x + 4.
Find the value of the function at x = 1.
y (1) = 2 * 1 + 4 = 6.
Find the value of x at y = 0.
0 = 2 * x + 4.
x = -4 / 2 = -2.
Determine whether the graph of the function passes through the point A (0, -2).
Y (0) = 2 * 0 + 4 = 4.
-2 ≠ 4.
Point A does not belong to the graph of the function.
