Solve question 8

Solve question 8: Let p be the piecewise defined function p(x) = 3 - 2g(x) for x < 3 and p(x) = 5k + f(x) for x ≥ 3. Find the value of k that makes p continuous at x = 3.

Solution

To solve question 8, we need to find the value of kk that makes p(x)p(x) continuous at x=3x = 3.

The piecewise function is given as:

3 - 2g(x), & x < 3 \\ 5k + f(x), & x \geq 3 \end{cases}$$ To ensure continuity at $$x = 3$$, the left-hand limit (as $$x \to 3^-$$) must equal the right-hand limit (as $$x \to 3^+$$), and both must equal the value of the function at $$x = 3$$. ### Step 1: Evaluate the left-hand limit as $$x \to 3^-$$ For $$x < 3$$, the function is $$p(x) = 3 - 2g(x)$$. Therefore: $$\lim_{x \to 3^-} p(x) = 3 - 2g(3)$$ From the graph of \( g(x)
