Answer: x = -1/2 = -0.5
Step-by-step explanation:
set up an equation
4x + 7 = 5 subtract 7 from both sides
4x = - 2 divide both sides by 4
x = -2/4
x = -1/2 = -0.5
Answer: (-6, infinty)
Step-by-step explanation:
So f(x)=3
that means that whatever you input for x, you will always get 3
the graph is a horizontal line that goes through the point (0,3)
it is the same equation as y=3
Answer:
Domain → (-∞, ∞)
Range → (-2, ∞)
Step-by-step explanation:
1). Domain of a function is defined by the input values (set of x-values) and Range of the function is defined by the output values (set of y-values).
From the graph attached,
Function is defined for all real values of x.
Therefore, domain of the function will be (-∞, ∞).
On y-axis values of the function vary from -2 (excluding 2) to positive infinity.
Therefore, range of the function will be (-2, ∞).
2). Average rate of change of a function in the interval (a, b) is defined by,
Average rate of change = 
By using this expression we can find the average rate of change in the given interval.
Please give the correct interval for which the average rate of change is to be calculated.
