Question

Given f(x) = x2 - 2x + 3, find the value(s) for x such that f(x) = 18. The solution set is o​

Answer 1

Explanation:

f(x) = x^2 - 2x + 3

f(x) = 18

x^2 - 2x + 3 = 18

x^2 - 2x + - 15 = 0

(x-5) (x+3) = 0

x = 5 (or) x = -3

not sure of the answer^^

Answer 2

0

Explanation:

Since f(x)=18 you would do:

f(x)= 18(2)-2(18)+3

f(x)=36-36+3

Final Answer: 0
