The numeric values of the function f(x) = 5x - 7 are given as follows:
a) f(-2) = -17.
b) f(1/2) = -9/2.
How to find the numeric value of a function/expression?
To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the function is not 100% visible from the picture, but we are going to suppose it is given by:
f(x) = 5x - 7.
At x = -2, the numeric value is:
f(-2) = 5(-2) - 7 = -10 - 7 = -17.
At x = 1/2, the numeric value is:
f(1/2) = 5(1/2) - 7 = 5/2 - 14/2 = -9/2.
