Final answer:
Given the function g(x) = -4x + 7, substituting the input value -5 into the function, we find the output to be g(-5) = 27.
Step-by-step explanation:
The student is asking to find the output value of a function g(x) = -4r + 7 for a given input value. The input value provided is -5. However, there seems to be a typo in the function expression - it's mentioned as 'r' instead of 'x'. Assuming the correct function is g(x) = -4x + 7, we will substitute x with -5 and calculate the output value.
Now substitute the known quantity into the equation and solve:
g(-5) = -4(-5) + 7
g(-5) = 20 + 7
g(-5) = 27
The missing value, which is the output of the function g for the input value -5, is 27.
