Given the function f(x) = 4x² - 5x + 7, the output values of f(-2), f(-1), f(0), f(1) and f(2) are 33, 16, 7, 6 and 13 respectively.
Given the function is the question;
To determine the output value of f(-2), replace all occurrence of x with -2 in the function and simplify.
f(x) = 4x² - 5 x + 7
f(-2) = 4(-2)² - 5(-2) + 7
f(-2) = 4×4 + 10 + 7
f(-2) = 16 + 10 + 7
f(-2) = 33
To determine the output value of f(-1), replace all occurrence of x with -1 in the function and simplify.
f(x) = 4x² - 5 x + 7
f(-1) = 4(-1)² - 5(-1) + 7
f(-1) = 4×1 + 5 + 7
f(-1) = 4 + 5 + 7
f(-1) = 16
To determine the output value of f(0), replace all occurrence of x with 0 in the function and simplify.
f(x) = 4x² - 5 x + 7
f(0) = 4(0)² - 5(0) + 7
f(0) = 0 + 0 + 7
f(0) = 7
To determine the output value of f(1), replace all occurrence of x with 1 in the function and simplify.
f(x) = 4x² - 5 x + 7
f(1) = 4(1)² - 5(1) + 7
f(1) = 4×1 - 5 + 7
f(1) = 4 - 5 + 7
f(1) = 6
To determine the output value of f(2), replace all occurrence of x with 2 in the function and simplify.
f(x) = 4x² - 5 x + 7
f(2) = 4(2)² - 5(2) + 7
f(2) = 4×4 - 10 + 7
f(2) = 16 - 10 + 7
f(2) = 13
Given the function f(x) = 4x² - 5x + 7, the output values of f(-2), f(-1), f(0), f(1) and f(2) are 33, 16, 7, 6 and 13 respectively.
