Answer:
154
Step-by-step explanation:
4x^2 – 7x + 7
4(7)^2 – 7(7) + 7 .....replace x with 7 and put it in the equation
196 -49 + 7
f(7) = 154
f(x) = 4x² – 7x + 7
f(7) = 4(7)² - 7(7) + 7
=> f(7) = 4(49) - 49 + 7
=> Taking 49 common,
=> f(7) = 49(4 - 1) + 7
=> f(7) = 49(3) + 7
=> f(7) = 147 + 7
=> f(7) = 154
