Question

Sample 2 - Test Excerpt Subject: Grade 10 Math Topic: Quadratic Functions Instructions: Solve each problem. Show your solution. 1. A ball is thrown upward with a velocity of \( 20 \mathrm{~m} / \mathrm{s} \) from a height of 5 meters. The height of the ball after \( t \) seconds is given by the equation \( h(t)=-5 t^{2}+20 t+5 \). - Find the maximum height of the ball. 2. Find the vertex of the parabola \( y=2 x^{2}-4 x+1 \). 3. Given \( y=x^{2}+6 x+9 \), identify the vertex and axis of symmetry. 4. Which of the following graphs represents \( y=-x^{2}+4 x-3 \) ? (Options show four graphs - two are not related to the given equation.)
