Question

If f(x) = 4x + 2 and x = (-3,-1,4.8}, what are the y values?

a)(14.6.-14.-30)
b)(-10.-2, 18, 34) c)(10.2.-18. -34)
d)(-14, -6, 14.30]​

Answer 1

After plugging in the given x values into the function f(x) = 4x + 2, the resulting y values are {-10, -2, 21.2}, which do not correspond to any of the provided answer choices.

Step-by-step explanation:

To find the y values for the function f(x) = 4x + 2 when x = {-3, -1, 4.8}, plug each x into the function and solve for f(x).

• For x = -3: f(-3) = 4(-3) + 2 = -12 + 2 = -10
• For x = -1: f(-1) = 4(-1) + 2 = -4 + 2 = -2
• For x = 4.8: f(4.8) = 4(4.8) + 2 = 19.2 + 2 = 21.2

Thus, the y values corresponding to x = {-3, -1, 4.8} are {-10, -2, 21.2}, which doesn't match any of the given options.
