PLEASE HELP WILL GIVE BRAINLIEST. Which of the following statments is true about the equation shown? Mark all that are true. t (
Vesna [10]

Answer:

a and c

Step-by-step explanation:

The equation of a quadratic in vertex form is

f(x) = a (x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 5)² + 7 ← is in vertex form

Thus the function is quadratic → a

• If a > 0 then the grapg will open upwards

• If a < 0 then the graph will open downwards

Here a = 1 > 0 then graph will open upwards → c

What is the domain, range, and function? {(-3, 3), (1, 1), (0, -2), (1,4), (5, -1)}
wolverine [178]

The domain are all the inputs, that is; the x-values

Domain = { -3, 0, 1, 5}

The range are all the output, that is the y-values

Range = { 3, 1, -2, 4, -1}

This is just a relation and not a function, as we have more than 2 same value of x
