Graph of f(x) = -2x + C passes through (-2,7)
How do I find C.
TIA
Since f(x) = 7 when x is -2,
7 = -2(-2) + C = 4 + C
C = 3
To find C, we can substitute the value of x (-2) and the corresponding y-coordinate (7) into the equation f(x) = -2x + C.
We have:
7 = -2(-2) + C
Now, let's simplify the equation:
7 = 4 + C
To isolate C, we can subtract 4 from both sides of the equation:
7 - 4 = C
C = 3
Therefore, the value of C is 3.
