Answer: the answer is option B. or h(x) = 9x - 18
Step-by-step explanation:
This equation can be solved graphically by plotting the equations
f(x) = 3^x
and
g(x) = 5x-1.
The x-coordinate of the point(s) of intersection is the solution.
_____
On my graphing calculator, I find it easier to locate x-intercepts, so I would rewrite the equation as
3^x -(5x -1) = 0
and plot the function
h(x) = 3^x -(5x -1)
The x-intercept(s) would be the solutions. (There are two: x≈0.577, x=2.)
First, find the slope of the line segment connecting the 2 given points:
10-(-2) 12
m = ----------- = --------- = 3
3-(-1) 4
Use the point-slope form: y-(-2) = 3(x-[-1]), or y = 2 + 3x - 3, or y = 3x - 1
Can you now fill in the blanks properly?
