Can anyone help me pls help me

Explanation:

A quadratic equation may have two different real solutions, two equal real solutions, or two complex (conjugated) solutions.

The graph of a quadratic function with two different real solutions crosses the x-axis at two points, which are the x-intercepts.

The graph of a quadratic function with two equal real solutons touches the x-axis at one point, which is the x-intercept.

The graph of a quadratic function with two complex solutions does not touch or cross the x-axis: it does not have x-intercepts.

Look at the determinant of the equation: it is the amount inside the root:

That is a positve number ( > 0). When the discriminant is greater than zero, the equation has to different real solutions, which are the x-intercepts of the graph.

Hence, in this case, Cody can use the graph because the x-intercepts are the solutions of the equation.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
