A student showed the steps below while solving the equation 14 = log Subscript 5 Baseline (2 x minus 3) by graphing. Step 1: Write a system of equations: y 1 = 14; y 2 = log Subscript 5 Baseline (2 x minus 3) Step 2: Use the change of base formula to rewrite the equations: y 1 = log 14; y 2 = StartFraction log (2 x minus 3) Over log 5 EndFraction Step 3: Graph the two equations: On a coordinate plane, a curve starts in quadrant 4 and curves up into quadrant 1 and approaches y = 2. It crosses the x-axis at (2, 0). A horizontal straight line is at y = 1. Step 4: Identify the x-value at the point of intersection: x almost-equals 4.5 In which step did the student make the first error? step 1 step 2 step 3 step 4
