f(x)=2x+1f(x)=-3x-4A. f(-3)B. f(1)C. f(4)​

Step-by-step explanation:Evaluating Functions To evaluate a function, we substitute the input value (x) into the function's formula and simplify. A. f(-3) For f(x) = 2x + 1: Substitute x = -3:f(-3) = 2(-3) + 1Simplify:f(-3) = -6 + 1f(-3) = -5 For f(x) = -3x - 4: Substitute x = -3:f(-3) = -3(-3) - 4Simplify:f(-3) = 9 - 4f(-3) = 5 Therefore, f(-3) = -5 for the first function and f(-3) = 5 for the second function. B. f(1) For f(x) = 2x + 1: Substitute x = 1:f(1) = 2(1) + 1Simplify:f(1) = 2 + 1f(1) = 3 For f(x) = -3x - 4: Substitute x = 1:f(1) = -3(1) - 4Simplify:f(1) = -3 - 4f(1) = -7 Therefore, f(1) = 3 for the first function and f(1) = -7 for the second function. C. f(4) For f(x) = 2x + 1: Substitute x = 4:f(4) = 2(4) + 1Simplifyf(4) = 8 + 1f(4) = 9 For f(x) = -3x - 4: Substitute: x = 4: f(4) = -3(4) - 4Simplifyf(4) = -12 - 4f(4) = -16 Therefore, f(4) = 9 for the first function and f(4) = -16 for the second function.
