Exponential functions

[rare glen]

no sure how to do this one

[drifting zodiac]

ok so

U need to form simultaneous equations

so

sub in your values of x and y

for each point

into the equation

twice

so 375 = p x q^4

& 3 = p x q^1

now divided to cancel p

and law of indices means it will be q^3

q^3 = 125

so solve for q

[rare glen]

ahhhh makes sense now

[drifting zodiac]

and then just sub in and u can find p

[rare glen]

thank youu

[drifting zodiac]

Np np

I like these questions

what did u get for value of p?

[rare glen]

oh sorry i'll do it now

[drifting zodiac]

nah im just curious to see if i got it right

its calm

[rare glen]

0.6

i checked the mark scheme it is 0.6

[drifting zodiac]

yhhhh

I got that

lovely

[civic ginkgo]

Yh it’s always

Sub in both points given

Yh I would advise to do it simultaneously
