For the function, what is the output of the given input?
a. For f(x) = 4x - 3, find f(-3).
b. For f(x) = 3+ 8x, find f
1}
4)
c. For f(x) =15x |, find f(0).
a. For f(x) = 4x - 3, the input is -3. Plugging in -3 into the function, we get f(-3) = 4(-3) - 3 = -12 - 3 = -15. So the output for f(-3) is -15.
b. For f(x) = 3 + 8x, the input is 1. Plugging in 1 into the function, we get f(1) = 3 + 8(1) = 3 + 8 = 11. So the output for f(1) is 11.
c. For f(x) = 15x, the input is 0. Plugging in 0 into the function, we get f(0) = 15(0) = 0. So the output for f(0) is 0.
