Find the solution, vertex, range, domain, and y-intercept of the quadratic function.

Solutions are x intercepts
factor
what 2 numbers multiply to 1 and add to -2? -1 and -1
(x-1)(x-1)=0
set to zero
x-1=0
x=1

vertex
get into y=a(x-h)^2+k form
how nice, it is actually
y=1(x-1)^2+0
the vertex is (1,0)
and since 1 is positive, it opens up and the vertex is a minimum

range is the y values
the min value is y=0
max is inifnity
range is from 0 to infinity

domain is the numbers you can use
use can use all real numbers

It should be amark me brainliest

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
