Given the equation f(x) = (x + 3)2 – 8, fill in the blanks: Axis of symmetry: x = a0 Vertex: ( a1, a2) Number of real solutions: a3

We have been given an equation .  We are asked to fill in the blanks using our given equation.

The axis of symmetry will be the vertical line passing through vertex.

First of all, we will convert our given equation in standard vertex form of parabola as:

Standard vertex form of parabola: , where (h,k) is vertex of parabola.

Upon comparing our function with standard vertex form, we can see that vertex of parabola is at .

The axis of symmetry will be vertical line passing through point . The vertical line will pass through , therefore, the axis of symmetry is .

Since our given parabola is an upward opening parabola, so it has a minimum at . This means that parabola will intersect the x-axis at two points. Therefore, there are two real solutions for the given function.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
