Fx=3x
Because f times x equals fx which could be equal to x+1 which is 1x plus 2 which is 3x leaving a product of fx=3x
8 months; $740
75x+140=90x+20
Find x then plug it in to find the cost
Answer:
Domain: [0, ∞)
Range: [7850, ∞)
Step-by-step explanation:
A function is defined by the set of ordered pairs having different output values for every input value.
In the graph attached, for every input value (x-coordinates) there is a unique output (y-coordinates) value.
Therefore, graph represents a function.
Domain of the given function → [0, ∞)
Range of the function → [7850, ∞)
