Answer:
x = - 4, x = 6
Step-by-step explanation:
Given
f(x) = x² - 2x + 3 and f(x) = 27, then equating the 2 gives
x² - 2x + 3 = 27 ( subtract 27 from both sides )
x² - 2x - 24 = 0 ← in standard form
Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 2)
The factors are - 6 and + 4, since
- 6 × 4 = - 24 and - 6 + 4 = - 2, thus
(x - 6)(x + 4) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 4 = 0 ⇒ x = - 4
Answer:
f(x) = -1/2x + 8

have a good day
Answer:
Step-by-step explanation:
2. Each time x goes up on the left side 6 is removed from the right side f(x)= F(-6)
3. slope is y = -1/2 x + 4 the formula is y = mx+b so -1/2 x and b is the number that touches the line for y which is 4.
4. every time an x is added on the left side 3 are added on the right side f(3)
The third option would be the incorrect one
