Step-by-step explanation:

Subtract 1 from both sides to get x alone. So, you have f(x) - 1 = x^2.
Now, square root both sides to remove the squared from x. So, you have...
$\sqrt{f(x) - 1} \: is \: x$

What is the value of the function at x = 2?<br> Enter your answer in the box.

Vedmedyk [2.9K]

Check the graph and observe where x = 2.

And check where it cuts across the line of the graph.

If you trace the graph carefully, when x = 2, y = -2

So the value of the function is -2.

I hope this helps.

using the giving information to write an equation. let X represent the number described in the exercise.then solve the equation

ANEK [815]

A number is multiplied by 8 and the result is 28.

A number= x.

8(x)= 28

Divide both sides by 8.

28/8= 3.5

x= 3.5

I hope this helps!

Answer:

The answer is (x,y)=(-10,-7)

Step-by-step explanation:

The solution comes from replace x= -10 into the equation of y=2/5 x -3.
Replacement of x= -10 into y = 2/5 x -3 results: $y=\frac{2}{5}\times{(-10)}-3=2\times{(-2)} -3=-4-3=-7$ .

Answer:

$\text{D. }b^2-4ac>0$

Step-by-step explanation:

The equation $b^2-4ac$ represents the discriminant of a quadratic. It is the part taken from under the radical in the quadratic formula.

For any quadratic:

If the discriminant is positive, or greater than 0, the quadratic has two solutions

If the discriminant is equal to 0, the quadratic has one distinct real solution (the solution is repeated).

If the discriminant is negative, or less than 0, the quadratic has zero solutions

In the graph, we see that the equation intersects the x-axis at two distinct points. Therefore, the quadratic has two solutions and the discriminant must be positive. Thus, we have $b^2-4ac>0$ .
