Answer:

Part A: f(4) = 2

Part B: k = -7

Step-by-step explanation:

f(4) simply means what the y-value of the graph is when x = 4.

The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.

Part B asks to solve the equation: f(4) + k = -5

We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):

2 + k = - 5

Substract 2 from both sides:

k = -7
