Question

Find the vertex of the graph of the quadratic function. Determine whether the graph opens upward or downward find the y-intercept and sketch on the graph. f(x)= - x^2 + 4x +5

Answer 1

Answer: Opens downward, y intercept is (0,5)

Explanation:

Opens downward cause leading coefficient is negative.

y intercept is when x=0 and it is 5 so the y intercept point is (0,5)

Can't help you with sketching it but you can use desmos and see the sketch there once you click on graphing calculator
