Find a quadratic function f(x) = ax^2+ bx+ c whose vertex is (1,2) and y-intercept of ( 0,3 )

Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
