Concept explainers
To sketch: the graph of the function. Also state the domain, intercepts and range of the graph.

Answer to Problem 55RE
The intercepts are
The domain is the set of all real numbers The intercepts are
Explanation of Solution
Given information:
Given function
Calculation:
Graph the basic function
Shift the graph vertically down 4 units to get the graph of the function
Intercepts are the points where the graph touches or crosses the coordinate axes. In
So, the intercepts are
In the function, 4 is subtract from
The points on the graph have
So, the range of
Therefore, the intercepts are

Note: f(x) = g(x). a) If_lim ƒ(x) = ∞ and_lim g(x) = ∞,then_lim [ƒ(x) − g(x)] = 0 x→ 0+ x→0+ x→0+ b) If h(x) and g(x) are continuous at x = c, and if h(c) > 0 and g(c) = 0, then h(x) lim. will = x→c g(x) c) If lim f(x) = 0 and lim g(x) = 0 then lim f(x) does not exist. x-a x-a x→a g(x)arrow_forwardPls help ASAParrow_forward15. a) Consider f(x) = x-1 3x+2 and use the difference quotient to determine the simplified expression in terms of x, for the slope of any tangent to y = f(x). Also, determine the slope at x = 2. 15 b) Determine the equation of the tangent to f(x) at x = 2. Final answer in Standard Form Ax + By + C = 0, A ≥ 0, with no fractions or decimals.arrow_forward
