Question

Given the following function, find the vertex, y=5x^2-8x+6​

Answer 1

• The vertex is (0.8, 2.8)

------------------------------------

Given

• Function y = 5x² - 8x + 6

Find the x-coordinate of the vertex

• x = - b/(2a)
• x = - (-8)/(2*5) = 8/10 = 0.8

Find the y-coordinate of the vertex

• y = 5(0.8²) - 8(0.8) + 6 = 2.8
