I need help !! Equation Given Value Function Solution
y=5x-4
when x = 5

Equation Given Value Function Solution
y=-2/5x+3/8
when x=1/3

Equation Given Value Function Solution
y=3x+1
2 when x=4

when we have a function:

y = f(x)

Evaluating the function just means replace the independent variable (x) by a given number.

Then, for the first case we have:

y=5x-4

when x = 5

Here we just need to replace x by 5 in the equation for y.

y = 5*(5) - 4

y = 25 - 4 = 21

for the second case:

y= -2/5x+3/8

when x=1/3

We just need to replace x by 1/3 in the equation, we will get:

y = -2/(5*(1/3)) + 3/8

y = - 2*3/5 + 3/8 = - 6/5 + 3/8

Now we need to find a common multiple between 8 and 5, that common multiple is 8*5 = 40

Then we can rewrite:

y = - (6*8)/40 + (3*5)/40 = (-48 + 15)/40 = -33/40

Finally, for the third case:

Equation Given Value Function Solution

y=3x+1

when x=4

We just need to replace x by 4 in the equation, so we will get:

y = 3*4 + 1

y = 12 + 1 = 13
