Use the Desmos graph and equation to get the answer to the vertex, axis of symmetry (x=), x intercepts, and the y intercept 2
f(x)=x -10x+21

Vertex: (5,-4)

Axis of symmetry: x=5

X-intercepts: (3,0) and (7,0)

Y-intercept: (0,21)

Step-by-step explanation:

The vertex would be the tip of the parabola, so the vertex is (5,-4)

The axis of symmetry would be a line cutting a parabola in half indicated by the line x=5

X-intercepts are where a function passes through the x-axis or when y=0, so in this case, the x-intercepts are (3,0) and (7,0)

The y-intercept of a function is where a function passes through the y-axis or when x=0, so our y-intercept is f(0)=0²-10(0)+21=21, or (0,21)

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

the answer is ! ?
