Which function is the inverse of f(x) = 2x + 3?

Mathematics
1 answer:
butalik [34]3 years ago
6 0

Answer:Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=2x+6 f - 1 ( x ) = 2 x + 6 is the inverse of f(x)=12x−3 f ( x ) = 1 2 x - 3 .

Step-by-step explanation:

The function: f(x) 2x+3

Put "y" for "f(x)": y 2x+3

Subtract 3 from both sides: y-3 2x

Divide both sides by 2: (y-3)/2 x

Swap sides: x (y-3)/2

Weird question. logically, the only answer that can make sense is a negative one since it is a decreasing slope. the secant is the average rate of change (and is 1/tangent) the tangent is the instantaneous rate of change. (1/secant) we want the first one which is:<span><span><span><span>Δx</span><span>Δy</span></span>=<span><span>Δ weeks</span><span>Δ lbs</span></span>=<span><span>5−0</span><span>137−150</span></span>=<span>5<span>−13</span></span>=−0.3846</span></span>
