Question
look at the table of values for the functions $f(x) = -2x + 2$ and $g(x) = \left(\frac{1}{4}\
ight)^x$.\
\
| $x$ | $f(x)$ | $g(x)$ | \ |
| --- | --- | --- | \ |
| $-2$ | $6$ | $16$ | \ |
| $-1$ | $4$ | $4$ | \ |
| $0$ | $2$ | $1$ | \ |
| $1$ | $0$ | $\frac{1}{4}$ | \ |
| $2$ | $-2$ | $\frac{1}{16}$ | \ |
\
based on the values in the table, where does the equation $f(x) = g(x)$ have a solution?\
\
$x = -2$\
$x = -1$\
between $x = -2$ and $x = -1$\
between $x = -1$ and $x = 0$
Step1: Check x = -2
For \( x = -2 \), \( f(-2) = 6 \) and \( g(-2) = 16 \). Since \( 6
eq16 \), \( x = -2 \) is not a solution.
Step2: Check x = -1
For \( x = -1 \), \( f(-1) = 4 \) and \( g(-1) = 4 \). Here, \( f(-1)=g(-1) \), so \( x = -1 \) is a solution.
Step3: Analyze other intervals
- Between \( x=-2 \) and \( x=-1 \): At \( x=-2 \), \( f(x)=6 \), \( g(x)=16 \) (\( f(x)<g(x) \)); at \( x=-1 \), \( f(x)=4 \), \( g(x)=4 \) (\( f(x)=g(x) \)). But we already found \( x=-1 \) is a solution, so this interval is not the answer.
- Between \( x=-1 \) and \( x=0 \): At \( x=-1 \), \( f(x)=g(x)=4 \); at \( x = 0 \), \( f(0)=2 \), \( g(0)=1 \) (\( f(x)>g(x) \)). But \( x=-1 \) is a solution, so this interval is not the answer.
