💥 Q 20: Prep 3 Algebra Question Bank T1

For the quadratic function \( f \) represented in the figure, select the correct combination:

1. Domain, Range, Symmetry, Max, f(1), a+k

(a) ℝ, ]-∞,4], x=0, 4, 3, 4

(b) [0,∞], ]-∞,4.5], x=1, 4.5, 4, 4.5

(c) ℝ, ]-∞,4.5], x=2, 4.5, 4, 4.5

(d) ℝ, [4.5,∞], x=2, 4.5, 4, 6.5

From the graph we find:
• Domain: \( \mathbb{R} \)
• Range: \( ]-\infty, 4.5] \)
• Line of symmetry: \( x = 2 \)
• Maximum value: 4.5
• \( f(1) = 4 \)
• \( a + k = 4.5 \)
