In the table below, y is a linear function of x. x(-2, 1, 4, 7, 10)
y( 0, 9, 18, 27, 36)

What is the y-intercept of the function?

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

Me because some of question i don’t understand

An angle that measures between 90 and 180° is called a(,
