The graph of the quadratic function shown on the grid. Which statement appears to be true?

The equation of the axis of symmetry of the graph of the function is x = 1

The maximum value of the function is 3.

The vertex of the graph of the functions is (4,1).

Which statement about $$f\left(x\right)=4x^2-36x+81$$ is true?

The only zero is $$\frac{9}{2}$$ because $$f\left(x\right)=\left(2x-9\right)^2$$

The zeros are $$\frac{3}{4}$$ and $$-27$$ because $$f\left(x\right)=\left(4x-3\right)\left(x-27\right)$$ .

The zeros are $$-\frac{3}{2}$$ and $$\frac{27}{2}$$ because $$f\left(x\right)=\left(2x+3\right)\left(2x+27\right)$$

The zeros are $$\pm\frac{9}{2}$$ because $$f\left(x\right)=\left(2x-9\right)\left(2x+9\right)$$ .

Given $$f\left(x\right)=x^2-36$$ , which statement is true?

The zeros, $$-6$$ and $$6$$ , can be found when $$0=\left(x+6\right)\left(x-6\right)$$ .

The only zero, $$6$$ , can be found when $$0=\left(x-6\right)\left(x-6\right)$$

The only zero, $$18$$ can be found when $$0=\left(x-18\right)\left(x-18\right)$$

The zeros, $$-18$$ and $$18$$ , can be found when $$0=\left(x+18\right)\left(x-18\right)$$ .

Function k is defined as $$k\left(x\right)=x^2+32x+248$$ . What are the solutions to $$k\left(x\right)=0$$ ?

$$x=-16+2\sqrt[]{2}$$ and $$x=-16-2\sqrt[]{2}$$

$$x=16+2\sqrt[]{2}$$ and $$x=16-2\sqrt[]{2}$$

$$x=-32+4\sqrt[]{2}$$ and $$x=-32-4\sqrt[]{2}$$

$$x=32+4\sqrt[]{2}$$ and $$x=32-4\sqrt[]{2}$$
