Answer:

(d) f(x) = 2x^2 - 16x + 35

Step-by-step explanation:

The x-coordinate of the extreme will be found at ...

x = -b/(2a)

where the function is f(x) = ax²+bx+c.

The extreme will be a minimum when a > 0. (eliminates choices A and B)

The x-coordinates of the extremes are ...

C: -(-4)/(2(4)) = 1/2

D: -(-16)/(2(2)) = 4 . . . . . matches the requirement

The appropriate choice is ...

f(x) = 2x^2 - 16x + 35

Which function rule represents the data in the table?

likoan [24]

Y = mx + b
b: y-intercept (when x equals zero)
m: slope ((y₂ - y₁) ÷ (x₂ - x₁))

Y - Intercept:
To find the y-intercept, just look at the table. The y-intercept is whatever y equals when x equals zero. In this case it is -8.

Slope:
(y₂ - y₁) ÷ (x₂ - x₁)
Pick two points and substitute them into this equation. Let's use (-3, 1) and (-2, -2).
(-2 - 1) ÷ (-2 + 3)
-3 ÷ 1
-3

Now substitute these values back into the equation.
y = mx + b
y = -3x - 8

The answer is a.
