Please help me solve this I don’t understand it at all

Factored Form: y = ( x + 3 ) ( x + 5 ) ( Factor using the AC method)

X-intercepts: ( - 3, 0 ) , ( - 5 , 0) ( To find the x-intercept, substitute in 0 for y and solve for x)

Axis of symmetry: x = - 4

Vertex:  ( - 4 , - 1 ) ( Rewrite in vertex form and use this form to find the vertex) (h , k).

Domain: ( - infinite sign, infinite sign ) , { x | x E R }

Range: y>=-1

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

the two may have that, even a breakdown is probably offered
