from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.
the third point, (0,-6), to the base is your height
use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8
area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12
Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis
Answer:
f(x) = x² + 9x - 22
Step-by-step explanation:
Given that x = 2 and x = - 11 are zeros, then
(x - 2) and (x + 11) are factors
and f(x) equals the product of the factors
f(x) = (x - 2)(x + 11) ← expand factors
f(x) = x² + 9x - 22 ← is a possible function
The graph's function, which depicts an exponential function, needs a domain of x ≥ 1. It's best to choose C.
We must choose which of the three functions in the graph of a function that has three distinct functions for its domain represents an exponential function.
An exponential function is what?
The domain of this exponential function is defined by the formula
f(x) = y = a∧x where a is a constant and x is a variable.
Since the graph continuously drops to -4 as shown throughout, it then displays a parabolic function from -4 to 0.9 before beginning to increase exponentially.
Consequently, the x domain is necessary for the function shown on the graph, which represents the exponential function. The ideal response is C.
