$color(blue)("The instruction is to solve graphically")$

Observe that the graph coincides with the x-axis at x=7

So $" "-x^2+14x-49 = 0" at "color(blue)(x=7)$

Construct a table of values

Using these values plot $x$ against $y$

Observe that the graph coincides with the x-axis at x=7

So $" "-x^2+14x-49 = 0" at "x=7$

How do you solve -x^2 + 14x - 49 = 0-x^2 + 14x - 49 = 0 graphically?
