Expressions cannot be solved.
Although they are similar to equations, you can solve an equation, but you cannot solve an expression. You can evaluate it, simplify it, and it can have many variables, however, an expression just exists, it is not a problem that has to be solved.

This relationship is not a function. Choose the sentence or

IRINA_888 [86]

Answer:

The input x = 1 has many outputs.

The graph is a vertical line.

Step-by-step explanation:

Hi there!

A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.

Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.

More generally, no vertical line is a function for this reason.

I hope this helps!

In which form is the following function written? y+20=8(x+7)^2

Wewaii [24]

Answer:

(a variation of) vertex form

Step-by-step explanation:

For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...

y = a(x -h)^2 +k

If k is subtracted from this equation, an alternate form is ...

y -k = a(x -h)^2

This latter version of vertex form is the form your equation has, where ...

a = 8
(h, k) = (-7, -20)
