Question

Evaluate the following functions.

f(x)=3x+2
f(x)=2x ^2 - x+5
A) 7, 4
B) 5, -6
C) 5, 8
D) 9, 7

Answer 1

To evaluate the functions 3x + 2 and 2x^2 - x + 5, substitute the given values of x into the functions and calculate the corresponding values of f(x).

Step-by-step explanation:

To evaluate the function f(x) = 3x + 2, substitute the given values of x into the function. For example, when x = 7, f(7) = 3(7) + 2 = 21 + 2 = 23. Similarly, for f(x) = 2x^2 - x + 5, substitute the values of x into the function to find the corresponding values of f(x).

For option A) 7, 4:
f(7) = 3(7) + 2 = 23; f(4) = 3(4) + 2 = 14 + 2 = 16

Therefore, the answer is Option A) 7, 4.
