Solve each equation by graphing the related function. If the equation has no real-number solution, write no solution.
x 2 + 49 = 0
To find: The real solution of the given equation.
There is no solution.
Given information: Solve given equation by graphing the related function. If the equation has no real-number solution, write no solution.
Calculation:
Equation x2+49=0
Graph of function f(x)=x2+49
Since the graph never touches the x−axis , f(x)=x2+49 will never be true. There is no solution.
