Not, it is a quadratic equation
Not a function
Please use " ^ " to denote exponentiation: x^2+y^2=5
This relation has the form x^2+y^2=r^2, which describes a circle of radius r and center at (0, 0). Draw a circle of any radius and then apply the vertical line test: draw a straight vertical line through the circle and count how many times the line intersects the graph.
If you do this properly you'll find that the vertical line intersects the circle in more than one place (that is, in two places).
This fails the vertical line test and tells us that x^2+y^2=5 does NOT represent a function.
your answer would be 10x - 1
the formula of a slope:
from a table we have
the slope of f(x) is -1.
the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.
-1 < 0answer: the function g(x) has the greatest slope.
